Answer:

Step-by-step explanation:

Pete played 18 tennis matches in a week.

P = 18

Jack played 6 fewer matches than Pete.

J = P - 6

J = 18 - 6

J = 12

How many times the number of matches pete played is the number of matches jack played?

18 / 12 = 1.5

Pete played 1.5 times the number of matches that Jack played.

Answer:

Pete played 1.5 times the amount of matches Jack did.

Step-by-step explanation:

In order to find this, first find the number that Jack played. Since he played 6 fewer than Pete we can solve by subtracting 6 from Pete's number.

18 - 6 = 12

Now to find how many more times higher it is, divide the number Pete does by Jack's number. 18/12 = 1.5

Answer:

192

Step-by-step explanation:

1/2 of 24 times 16=192

Answer:

Step-by-step explanation:

Put the values of x from the set {0, 1, 2, 3, 4} to the euation 5x + 6 = 6 and check it:

for x = 0:

5(0) + 6 = 6

0 + 6 = 6

6 = 6      TRUE

for x = 1:

5(1) + 6 = 6

5 + 6 = 6

11 = 6    FALSE

for x = 2:

5(2) + 6 = 6

10 + 6 = 6

16 = 6   FALSE

for x = 3:

5(3) + 6 = 6

15 + 6 = 6

21 = 6          FALSE

for x = 4:

5(4) + 6 = 6

20 + 6 = 6

26 = 6    FALSE

Answer:

[tex]\large\boxed{y=6x+9}[/tex]

Step-by-step explanation:

The slope-intercept form of the equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points E(-1, 3) and F(-2, -3). Substitute:

[tex]m=\dfrac{-3-3}{-2-(-1)}=\dfrac{-6}{-2+1}=\dfrac{-6}{-1}=6[/tex]

Therefore the equation of a line is:

[tex]y=6x+b[/tex]

Put the coordinates of the point E(-1, 3) to the equation and solve it for b:

[tex]3=6(-1)+b[/tex]

[tex]3=-6+b[/tex]             add 6 to both sides

[tex]9=b\to b=9[/tex]

Finally we have:

[tex]y=6x+9[/tex]

You'd need 0 pounds and 14 ounces of flour.

Answer:

[tex]\large\boxed{(x+3)^2+(y-2)^2=225}[/tex]

Step-by-step explanation:

The equation of a circle:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

(h, k) - center

r - radius

We have r = 15 and the center (-3, 2). Substitute:

[tex](x-(-3))^2+(y-2)^2=15^2\\\\(x+3)^2+(y-2)^2=225[/tex]

Your Welcome

As the x-values go to positive infinity, the function's values go to positive infinity.

Answer: D, As the x values go to positive infinity, the functions values go to positive infinity.

Step-by-step explanation:

This is true for just about any [tex]y=x^{3}[/tex] graph. As the value of the input (x) get larger, the value of the output (y) will get exponentially larger.

900 = 750 + 2*75. In other words, 900 is 2 standard deviations away from the mean. Similarly, 975 is 3 standard deviations from the mean. So

[tex]P(900<X<975)=P(2<Z<3)[/tex

where [tex]X[/tex] is the random variable for the lifespan of a light bulb with the given normal distribution, and [tex]Z=\dfrac{X-750}{75}[/tex] with the standard normal distribution.

We get

[tex]P(2<Z<3)\approx0.0214=2.14\%[/tex]

If you don't have a calculator/lookup table available, you can invoke the empirical rule, the one that says

[tex]\begin{cases}P(-1<Z<1)\approx68\%\\P(-2<Z<2)\approx95\%\\P(-3<Z<3)\approx99.7\%\end{cases}[/tex]

The normal distribution is symmetric about its mean, so we also know

[tex]\begin{cases}P(0<Z<1)\approx34\%\\P(0<Z<2)\approx47.5\%\\P(0<Z<3)\approx49.85\%\end{cases}[/tex]

Then

[tex]P(2<Z<3)=P(0<Z<3)-P(0<Z<2)\approx2.35\%[/tex]

Answer:

0.021

Step-by-step explanation:

One way in which to approach this problem solution is to use a calculator that has statistical distribution functions built in.  My old TI-83Plus has the function "normalcdf," which does the job nicely.

Typing in normalcdf(900,975,750,75) results in the probability 0.021 that a light bulb chosen at random will last between 900 and 975 hours.

Using a table of z-scores would be a good alternative approach.  Note that the z-score corresponding to 750 hours is 0; that for 900 is +2; and that for 975 is +3.  Find the area under the standard normal curve to the left of 975 (z = 3) and that to the left of 900 (z = 2), and then subtract the two results.  It will be 0.021, as before.

13 - 6 is 7

7 + 6 = 13

Just subtract the 2 numbers and you get your answer.

Final answer:

The equation 13 = 6 + y is solved by subtracting 6 from both sides, yielding y = 7.

Explanation:

To solve for y in the equation 13 = 6 + y, we need to isolate y on one side of the equation. We can do this by subtracting 6 from both sides of the equation.

Here is how you can solve the equation step by step:

Start with the original equation: 13 = 6 + y.

Subtract 6 from both sides: 13 - 6 = 6 + y - 6.

This simplifies to: 7 = y.

So, the value of y is 7.

Answer:

8x - 12y

Step-by-step explanation:

4(2x-3y)

Distribute/multiply the 4 to everything in the parentheses

4 * 2x = 8x      4 * -3y = -12y

8x - 12y

Answer:

[tex]4(2x-3y)=8x-12y[/tex]

Step-by-step explanation:

The given expression is

[tex]4(2x-3y)[/tex]

We expand using the distributive property to obtain;

[tex]4(2x-3y)=4\times2x-4\times3y[/tex]

This implies that;

[tex]4(2x-3y)=8x-12y[/tex]

This is a special right triangle with 3 sides that are 5, 12, 13. You should remember this triangle.

Answer:

x1 = - 4

x2 = 2/3

Step-by-step explanation:

Divide the equation by 3 to give

x^2 + 10x/3 + c/3 = 0

The sum of the two roots = - 10/3

So

x1 + x2 = -10/3

x1 - x2 = 4 2/3                Add these two equations.

2x1 = -10/3 + 4 2/3         Change 4 2/3 to an improper fraction

2x1 = -10/3 + 14/3            Combine the right

2x1 = 4/3                         Divide by 2

2x1/2 =4/3//2        

x1 = 2/3

=====================

x1 + x2 = - 10/3

2/3 + x2 = - 10/3

x2 = - 10/3 - 2/3

x2= -12/3

x2 = - 4

=================

(x - 2/3)(x +4) = 0              Multiply through by 3

(3x - 2)(x + 4) =0

==============

Check

(3x - 2)(x + 4) = 0

3x^2 + 12x - 2x - 8 =0

3x^2 + 10x - 8 = 0

Step-by-step explanation: removing the tile she just flipped over would be 6 plants and 2 animals so there would be 8 total tiles and you would putt the remaining tiles over it like so 6/8 meaning out of the remaining 8 tiles 6 of them are plants giving her a 6 in 8 chance or a 3 in 4 chance

Answer:

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

We are given that Maggie has 7 tiles with pictures of plants and 2 tiles with pictures of animals .

Number of tiles with picture of plants =7

Number of tiles with picture of animals =2

Total number of tiles =7+2=9

We have to find the probability that the second tile that Maggie turns over has  plant on it .

When she removes one tile of picture of plant then she has number of tiles of picture of plants =6

Total number of tiles =8

Probability,P(E)=[tex]\frac{Number\;of\;favorable\;cases}{Total\;number\;of\;cases}[/tex]

Using the formula then we get

The probability that she finds tile of picture of plant =[tex]\frac{6}{8}=\frac{3}{4}[/tex]

FIND A PATTERN IN THE NUMBERS

Answer:

The answer is 53

Step-by-step explanation:

The mathematical representation of '5 is 5% of what number?' is 5 = 0.05w. To solve for w, we divide 5 by 0.05, which gives us a value of w=100.

To solve the question, '5 is 5% of what number w?', we can set up the equation as 5 = 0.05w. This equation represents the statement '5 is 5% of some number w' in mathematical terms. To find the value of w, we divide both sides of the equation by 0.05. The calculation goes like this:

https://brainly.com/question/16797504

#SPJ12

The equation to find the number for which 5 is 5% is: 5 = 0.05w. The solution to the equation is w = 100.

To write and solve the equation that represents the given statement, we can let 'w' represent the unknown number.

The equation is:

5 = 0.05w

Solving for w, we divide both sides by 0.05:

w = 5 / 0.05

w = 100

Therefore, the solution to the equation is w = 100. This means that 5 is 5% of 100.

where

SS is sum of squares

s^2 is the variance, and

n is the number of data points

We are given all the info to find out s^2. Hence,

[tex]s^2=\frac{SS}{n-1}\\s^2=\frac{162}{15-1}\\s^2=\frac{162}{14}=11.57[/tex]

First we have to find 25% of 900 pounds (i hope that's the right currency). so 900 x .25 = 225

so we subtract 225 from 900 and get 675 pounds.

to find sales tax we have to find 6% of 675, so 675 x .06 = 40.50

675 + 40.50 = 715.5 pounds

Answer:

V = 5/8  cm^3
