Meghan counted the candies she had in a jar. She discovered that half of the candies were red. If she had 50 red candies, in which equation does x represent the total number candies in the jar?

Answer:

D

Step-by-step explanation:

Two events are independent if the intersection of the two events is the same as multiplying each events probability.

P (Texas) = 125/ 275 = 0.45

P (Brand A) = 176/275 = 0.64

0.45 * 0.64 = 0.29

P (Texas ∩ Brand A) = 0.29

So to find P (Texas | Brand A) = 0.29 / 0.64 = 0.45

Answer choice D makes the best choice.

Disclaimer: The number of cities in Asia will be 8 and not 888.

Elyse can choose from 960 different combinations of cities.

The different ways in which objects from a set can be picked, often without replacement, to produce subsets are known as permutations and combinations. When the order of selection is a factor, this selection of subsets is termed a permutation; when order is not a factor, it is called a combination.

We are given 4 continents, with a number of cities to choose from for Elyse to visit.

The table is like this:

Continent                          Number of cities

Europe                                           10

Asia                                                8

Africa                                              4

Australia                                         3

We use permutations and combinations to find the number of combinations Elyse will have to choose from.

We can say that for every 10 cities in Europe, she can choose any of the 8 cities in Asia. Similarly, for every 8 cities in Asia, she can choose any of the 4 cities in Africa. And similar is the case for Africa and Australia.

∴ Elyse can choose from a combination of 10*8*4*3 cities,

or, Elyse can choose from a combination of 960 cities.

Answer:

The correct one is b nice you chose the right one!

Step-by-step explanation:

Answer:

m<BED = 136 deg

Step-by-step explanation:

Since ray EC bisects <BED, angles BEC and CED are congruent. That means their measures are equal. Set the measures equal to each other, and solve for x.

11x + 2 = 8x + 20

Subtract 8x from both sides.

3x + 2 = 20

Subtract 2 from both sides.

3x = 18

Divide both sides by 3.

x = 6

Now we use the value of x to find the measure of angle BED.

The measure of angle BED is twice the measure of angle BEC. We know that x = 6.

m<BED = 2m<BEC = 2(11x + 2) = 2(11 * 6 + 2) = 2(66 + 2) = 2(68) = 136

Assuming 0x6A is given in base 16, first convert [tex]152_b[/tex] and [tex]6A_{16}[/tex] to a common base, say base 10:

[tex]152_b=1\cdot b^2+5\cdot b^1+2\cdot b^0=(b^2+5b+2)_{10}[/tex]

[tex]6A_{16}=6\cdot16^1+10\cdot16^0=106_{10}[/tex]

Then

[tex]b^2+5b+2=106[/tex]

[tex]b^2+5b-104=(b-13)(b+8)=0[/tex]

[tex]\implies b=13[/tex]

Answer:

The value of b is, 8

Step-by-step explanation:

Determine the value of b;

Given:

[tex](152)_b = 0x6A[/tex]             ....[1]

Since, 0x6A represents the hexadecimal form.

First convert this hexadecimal form into decimal form:

[tex](6A) = (6 \times 16^1)+(A \times 16^0) = (96)+(10 \times 1) = 96+10 = 106[/tex]

⇒[tex]0x6A = 106[/tex] (decimal form)

Now we have to convert this decimal form into octal

8  |  106

8   |  13   | 2

     |   1    | 5

          1

Then, the octal form we get, [tex](152)_8[/tex]

Substitute these in [1] we have;

[tex](152)_b=(152)_8[/tex]  

On comparing both sides we get;

b = 8

Therefore, the value of b is, 8

525

Because the nearest tenth is the number after the decimal point but then nine rounds up. If you don’t want the nine rounded up leave it as 524.9

In given number 524.95, place value of 9 is tenth. So, the nearest ten is 525.0

The place value is the position of each digit in a number.

The nearest tenth is the number after the decimal point but then nine rounds up. If you don’t want the nine rounded up leave it as 524.9

524.9 = 525.0

Therefore, the answer is 525.0

The two little lines through the two sides of the triangle mean that they are the same length.

When two sides of a triangle are the same, the two lower inside angles are also the same.

Angle A is given as 50 degrees, so angle C is also 50 degrees.

The sum of the three inside angles need to equal 180 degrees, so angle B would equal 180 - 50 - 50 = 80 degrees.

Angle B = 80

Answer:

651  2/12

Step-by-step explanation:

Answer: 6/5 and -6/5

Step-by-step explanation: In order to solve this problem, we want to get the variable on one side. In order to do that, we must do the following:

Add 36 on Both Sides:

[tex]25x^2 - 36+36 = 0+36[/tex]

Divide 25 on Both Sides:

[tex]\frac{25x^2}{25}= \frac{36}{25}[/tex]

Take the square root of Both Sides:

[tex]\sqrt{x^2} = \sqrt{\frac{36}{25} }[/tex]

That means your answer is:

[tex]x = \frac {6}{5}[/tex], or [tex] -\frac {6}{5} [/tex]

Answer:

34,860

Step-by-step explanation:

In a sample of 32 residence, 24 take Vitamin C. From here we can get the proportion of residents who take Vitamin C, which is 24/32 = 3/4 = 0.75

0.75 in  percentage is 75%. This means 75% of the residents in sample take Vitamin C.

We can expect the same percentage of people in entire population to take Vitamin C.

Total population of city = 46480

Expected number of residents who take vitamin C in the city = 75% of 46480

= 0.75 x 46480

= 34860

This means, 34860 is an estimate of number of city residents who take Vitamin C supplement daily.

Based on the sample study and assuming its representativeness of the general population, it is estimated that approximately 34,860 residents of the city take a vitamin C supplement daily.

In the sample study, the proportion of residents who take vitamin C supplements daily is calculated by dividing the number of individuals who reported taking the supplement (24) by the total number of individuals in the sample (32). This yields a proportion of 0.75, or 75%. Then, we can apply this proportion to the total population of the city to estimate the number of residents who take vitamin C daily. Therefore, the estimated number is 0.75 * 46,480 = 34,860.

In conclusion, assuming that the small sample is representative of the larger population, we would estimate that "approximately 34,860" city residents take a vitamin C supplement daily.

Answer:

Step-by-step explanation:

Objects that float on water have densities less than the density of water; those that do not float on water have densisties greater than the density of water:

Float on water:  d < 0.0361 lb/in³ (where d denotes denisity)

Do not float on water:  d > 0.0361 lb/in³

The densities of objects that float on water are lower than those of objects that don't float.

It is defined as the mass-to-volume ratio. The density indicates the object's density and is represented by the symbol. The density is measured in kilograms per cubic meter.

We have:

Water has a density of about 0.0361 pounds/cubic inch.

Let d be the density:

Float on water:  d < 0.0361 lb/in³

Do not float on water:  d > 0.0361 lb/in³

The densities of objects that float on water are lower than those of objects that don't, which have densities higher than those of water.

Thus, the densities of objects that float on water are lower than those of objects that don't float.

Answer: ∠D.

Step-by-step explanation:

because they are in the same position (2nd letter placement)

If quadrilaterals CDEF ≅ MNPQ, then it follows that ∠N ≅ ∠D.

Hence ∠D is correct.

If CDEF and MNPQ are congruent,

Then it means they have the same shape and size.

In other words, all of their corresponding angles and sides are equal.

Therefore, if ∠C is congruent to ∠M,

∠D is congruent to ∠N,

∠E is congruent to ∠P, and

∠F is congruent to ∠Q.

This is because congruence is a relation of equality between two geometric figures.

So, if two triangles (or any other polygons) are congruent,

Then all of their corresponding angles and sides are equal.

Therefore, if CDEF ≅ MNPQ, then it follows that ∠N ≅ ∠D.

Answer:

The vertical distance the ant have to walk is 8 units

Step-by-step explanation:

∵ The ant must be walk vertically and horizontally

∴ The distance from start point to end point will be as

   a hypotenuse of a right angle triangle

∵ The ant would have to walk 6 units horizontally that

   means one side of the right angle is 6 units

∵ The two points are apart by 10 units that means

   the length of the hypotenuse is 10 units

∴ The vertical distance the ant would have to walk is

   the length of the second side of the right angle

* By using Pythagoras Theorem:

∵ (hypotenuse)² = (horizontal leg)² + (vertical leg)²

∴ 10² = 6² + (vertical leg)²

∵ (vertical leg)² = 100 - 36 = 64

∴ Vertical leg  = √64 = 8 units

∴ The vertical distance the ant have to walk is 8 units

If we call the unknown number x, we have:

If this equals 34, we have

Step-by-step explanation:

1. According to the properties of exponents, you have that:

[tex]a^{-n}=\frac{1}{a^n}\\\\(a^n)^m=a^{mn}[/tex]

2. Then, he must simplify the expression as following:

[tex](4z^8)^{-3}={4^{-3}z^{8(-3)}=\frac{1}{64z^{24}}[/tex]

3. Therefore, as you can see, should have also applied the negative exponent to 4 to get [tex](4z^8)^{-3}={4^{-3}z^{8(-3)}=\frac{1}{64z^{24}}[/tex]

Answer:

The correct answer option is He should have also applied the exponent -3 to 4 to get [tex]4^{-3}z^{8 \cdot(-3)} = 4^{-3}z^{-24} = \frac{1}{64z^{24}}[/tex].

Step-by-step explanation:

The following expression was to be simplified by Mario:

[tex] (4z^8)^-3 [/tex]

Given this expression, we need to apply this rule on it in order to simplify:

[tex] (a b)^m = a^m \cdot b^m [/tex]

So we would get:

[tex] (4z^8)^-3 [/tex]

[tex]4^{-3} \cdot (z^8)^{-3}[/tex]

[tex]\frac{1}{4^3} \cdot z^{-24}[/tex]

[tex]\frac{1}{64z^{24}}[/tex]

This would be the right simplification for the given expression but by looking at Mario's work shown, we can conclude that:

He should have also applied the exponent -3 to 4 to get [tex]4^{-3}z^{8 \cdot(-3)} = 4^{-3}z^{-24} = \frac{1}{64z^{24}}[/tex].
