(Solve for r) 0.5r − 3.8 = 5.66

Answers

0.5r - 3.8 = 5.66....add 3.8 to both sides
0.5r = 5.66 + 3.8
0.5r = 9.46...divide both sides by 0.5
r = 9.46 / 0.5
r = 18.92 <==
0.5r = 5.66 + 3.8
0.5r = 9.46
r = 9.46 ÷ 0.5
r = 18.92

r - 3 r
____ = __
10 13 Check:



Answers

Things are a bit cluttered. 
I'm assuming the equation should be (r-3)/10 = r/13.

Use parenthesis to indicate what is being divided. In this case all of "r-3" is over 10. 

If my assumption above holds up, then we can solve for r like so
(r-3)/10 = r/13
13(r-3) = 10r ... cross multiply
13r-39 = 10r
13r-39-13r = 10r-13r ... subtract 13r from both sides
-39 = -3r
-3r = -39
-3r/(-3) = -39/(-3) ... divide both sides by -3
r = 13

The value of r is r = 13

-----------------------

Check:

Replace every copy of "r" with "13" to get
(r-3)/10 = r/13
(13-3)/10 = 13/13
10/10 = 13/13
1 = 1 ... equation is true; answer has been confirmed

Final answer:

To solve the equation, we cross multiply to eliminate the fractions and solve for r. The solution is r = 13. We can check the solution by substituting it back into the original equation.

Explanation:

To solve the equation (r - 3) / 10 = r / 13, we can cross multiply to eliminate the fractions. This gives us 13(r - 3) = 10r. Distributing, we get 13r - 39 = 10r. We can then solve for r by subtracting 10r from both sides and adding 39 to both sides. This gives us 3r = 39. Dividing both sides by 3, we find that r = 13.

To check the solution, we substitute r = 13 back into the original equation. The left side becomes (13 - 3) / 10 = 10 / 10 = 1, and the right side becomes 13 / 13 = 1. Since both sides are equal to 1, we can confirm that the solution r = 13 is correct.

Is the data set “heights of the women in the U.S. Congress” quantitative or qualitative? If it is quantitative, is it discrete or continuous?

Answers

The data is quantitative because you can average the data. It is not a label.
It is continuous because there are more than integer values of heights.

Answer with explanation:

The  “heights of the women in the U.S. Congress” is Quantitative,because height of person does not represent Quality, it shows "Quantity".It means it has Magnitude.

We can find mean , median and mode of women in Congress.

So, Height of women in US congress is Quantitative.

As, different Women have different Heights, that is any rational number , so The Height of different women will be a discrete data set.For, example, height of different women can be={167 cm, 187.6, 176.6,165.5,.....}

How to go from sum of products to product of sums?

Answers

Multiplication gives us distribution over the products, so

 

(a′+b+d′) (a′+b+c′+f′) = a′ (a′+b+c′+f′) + b (a′+b+c′+f′) + d′ (a′+b+c′+f′)

 

And then you can then distribute again each of the factors on the right.

Then you should simplify in any given number of ways. To take as an example, you have a′b and ba′, and since a′b + a′b = a′b + a′b = a′b, you can just drop one of them. Since bb = b, you can rewrite bb as b and etc.

 

So in the end part we should arrive at a sum of products. Then you can just invert. For example, if at the end you had:

p′ = a′b + bc′ + d′f ′+ a′f′

 

Then we would have

p = p′′ = (a′b + bc′ + d′f′ + a′f′)′ = (a′b)′⋅(bc′)′⋅(d′f′)′⋅(a′f′)′

 

Then applying De Morgan's laws to each of the factors, e.g., (a′b)′ = a+b′, so we would have

p = (a+b′)⋅(b′+c)⋅(d+f)⋅(a+f)

which is a product of sums.

The answer is vertical.
Answer:

The transformation from f to g represents a Vertical stretch.

Step-by-step explanation:

We are given a parent function f(x) as:

                      [tex]f(x)=\sqrt{x}[/tex]

and the transformed function g(x) as:

        [tex]g(x)=6\sqrt{x}[/tex]

We know that any function transformation of the type:

      f(x) → a f(x)

represents either a vertical stretch stretch or compression depending on the value of a.

If   0<a<1 then the transformation is a vertical compression and if a>1 then the transformation is a vertical stretch.

Here we have a=6>1

Hence, the transformation is a VERTICAL STRETCH.

What is a geometric sequence?

In a geometric sequence, the ratio of two consecutive terms are always equal.

The general expression for the nth term is given as aₙ = a₁ × rⁿ⁻¹ .

The sum of n terms for this sequence is given as Sₙ = (rⁿ - 1)/(r - 1)

The given series is  400 + 200 + 100 + …

It is a geometric series.

Its first term is a₁ = 400.

And, common ratio is r = 200/400 = 0.5.

Now, the expression for the sum of n terms is given as below,

Sₙ = a(1 - rⁿ)/(1 - r)

Then, substitute the value of a₁, a₅ and n = 5 to obtain,

S₅ = 400(1 - 0.5⁵)/(1 - 0.5)

⇒ S₅ = 775.

Hence, the sum of first five terms of the given series is 775.

If measure of angle p=(10x-2),measure of angle o=(3x+9) , and measure of angle q=(3x-3) , list the lengths of the sides of triangle OPQ from longest to shortest.

Answers

The sum of all angles of a triangle must be equal to 180°

So we can find the value of x...

10x-2+3x+9+3x-3=180

16x+4=180

16x=176

x=11

So the angles are 108°, 42°, 30°

Now using the Law of Sines we can solve for all sides.

(sina/A=sinb/B=sinc/C)

a/sin30=b/sin42=c/sin108

However, we would need to know at least one side length to solve for sides a,b, and c numerically, otherwise it can be any multiple of an arbitrary choice for the smallest side.  Let a=1 for example:

b=sin42/sin30, c=sin108/sin30

b≈1.34,  c≈1.90

a=1, b=1.34, c=1.9

Anyway...

If you are given any side length:

a/sin30=b/sin42=c/sin108 still holds true and you can solve for the other side lengths...

Answer:

OQ > PQ > OP

Step-by-step explanation:

In this question measure of all angles in a triangle has been given.

m∠ p = (10x - 2)

m∠ q = (3x - 3)

m∠ o = (3x + 9)

Since total of all angles is 180°, so we will equate the total of all angles to 180°

∠p + ∠q + ∠o = 180°

(10x - 2) + (3x - 3) + (3x + 9) = 180°

(10x + 3x + 3x) -2 - 3 + 9 = 180

16x - (2 + 3 - 9) = 180°

16x + 4 = 180

16x = 180 - 4

16x = 176

x = [tex]\frac{176}{16}=11[/tex]

Now we will find the measure of each angle.

∠p = (10x - 2) = 10×11 - 2 = (110 - 2) = 108°

∠q = (3x - 3) = 3×11 - 3 = (33 - 3) = 30°

∠o = (3x + 9) = 3×11 + 9 = (33 + 9) = 42°

As we know in a triangle, angle opposite to the largest side is largest and angle opposite side is the smallest.

Since ∠p > ∠o > ∠q

Therefore, in Δ OPQ opposite sides to these angles will be in the same ratio.

OQ > PQ > OP

A basket contains 11 pieces of fruit: 4 apples, 5 oranges, and 2 bananas. Jonas takes a piece of fruit at random from the basket, and then Beth takes a piece at random. What is the probability that Jonas will get an orange and Beth will get an apple?

Answers

Final answer:

The probability that Jonas will get an orange and Beth will get an apple is 20/121.

Explanation:

To find the probability that Jonas will get an orange and Beth will get an apple, we need to find the probability of Jonas getting an orange and then multiply it by the probability of Beth getting an apple.

The probability of Jonas getting an orange is the number of oranges in the basket (5) divided by the total number of fruits (11):

P(orange for Jonas) = 5/11

The probability of Beth getting an apple is the number of apples in the basket (4) divided by the total number of fruits (11):

P(apple for Beth) = 4/11

To find the combined probability, we multiply these two probabilities together:

P(orange and apple) = P(orange for Jonas) * P(apple for Beth) = (5/11) * (4/11) = 20/121

Answers

true, you have to get heads previously in order to get 3 in a row

Answer with explanation:

Event Joining by two or more Simple events is called Compound Event.

When you throw a coin once, getting either Head or Tail is a Simple event.

And , when you throw a coin and dice together, getting , Head and 1 , is a Compound event.Because here we joined two simple events, one is Throwing of a coin and another one is throwing a dice.

When you toss a coin thrice, it is combination of three simple events, that is tossing of coin three times .So total possible outcome

      [tex]=2^3\\\\=8[/tex]

Which can be written as: {(HHH),(HHT),(HTH),(THH),(HTT),(THT),(TTH),(TTT)}

Probability of getting all heads on 3 coin tosses

What is the value of the fourth term in a geometric sequence for which a1 = 30 and r = 1/2?

Answers

Final answer:

The value of the fourth term in the geometric sequence is 3.75.

Explanation:

The value of the fourth term in a geometric sequence can be found using the formula:



an = a1 * r(n-1)



Given that a1 = 30 and r = 1/2, we can substitute these values into the formula and solve for a4:



a4 = 30 * (1/2)(4-1) = 30 * (1/2)3 = 30 * (1/8) = 3.75



Therefore, the value of the fourth term in the geometric sequence is 3.75.

Final answer:

The value of the fourth term in the geometric sequence is 3.75.

Explanation:

A geometric sequence is a sequence of numbers where each term is found by multiplying the previous term by a constant ratio. In this case, the first term (a1) is 30 and the common ratio (r) is 1/2. To find the fourth term, we can use the formula:

an = a1 * r(n-1)

Substituting the values given, we have:

a4 = 30 * (1/2)(4-1)

Simplifying this expression, we get:

a4 = 30 * (1/8) = 3.75

Therefore, the value of the fourth term in this geometric sequence is 3.75.

A pizza delivery shop averages 20 minutes per delivery with a standard deviation of 4 minutes. What is the probability that a pizza takes less than 15 minutes to be delivered?

Answers

We have the mean, μ = 20 and the standard deviation, σ = 4

X ≈ N(20, 4²)

We want P(X<15)

Standardising gives

P(X<15) = P(Z<[tex] \frac{15-20}{4} [/tex])
P(X<15) = P(Z< -1.25) ⇒ When the value of the z-score is negative, we will read the value of z<1.25 on the z-table then subtract the answer from 1

P(X<15) = 1 - P(Z<1.25)
P(X<15) = 1 - 0.8944
P(X<15) = 0.1056

Hence, the probability that pizza takes less than 15 minutes to be delivered is 0.1056 = 10.56%

A rectangular prism with a square base has a lateral area of 192 square yards and a surface area of 264 square yards. What is the length of a base edge?

Answers

A rectangular prism is like a cardboard shoe box. It has two equal bases, one on the top and the other on the bottom. It also has 4 lateral faces to close the figure. The surface area of the prism is the area of all its faces: the 4 side faces and the 2 bases. On the other hand, lateral surface area only accounts for the 4 lateral faces. Therefore, we can conclude that the total surface area is equal to the lateral surface area plus the areas of the two bases.

TSA = LSA + 2s²

Since the base is said to be the square, its area is equal to s² where s is the base edge. Because there are 2 bases, that's why it's 2s².

264 = 192 + 2s²
s² = (264-192)/2
s = √36
s = 6 yards

 

How to write 100000 in scientific notation?

Answer:

100000 in scientific notation:[tex]100,000=1.0\times 10^{5}m/s[/tex]

Step-by-step explanation:

Scientific notation is defined as the notation in which a number is expressed in the decimal form. This means that the number is always written in the power of 10 form. The numerical digit lies between 0.1.... to 9.9.....

If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.

We are given:  100,000

Converting this into scientific notation, we get:

[tex]\Rightarrow 100,000=1.0\times 10^{5}m/s[/tex]

As, the decimal point is shifting to left side, thus the power of 5 is positive.
