Answer:

You can bake 96 cookies in 32 minutes.

Step-by-step explanation:

Since we are given "if you can bake 15 cookies in 5 minutes" you dived 15 by 5 to find the unit rate. 15÷5=3

Since 3 is the unit rate we multiply it by 32, to get 96.

3×32=96

In other words, the unit rate is how many cookies you can make in a minute.

Step-by-step explanation:

The expression in the form of equation can be simplified as: 7w - 12y + 18

What is equation?

In mathematics, the statement based problems can be solved by forming the equations. And the equations consist of dependent variable as well as independent variables. It is calculated by equating the terms to zero.

According to the question, the given expression in the form of equation is as follows:

Required expression: 8w - 12 y + 15 divided by 3 + w - 6

The given expression can be re-written as:

Required expression: (8w - 12y + 15)/(3 + w - 6) = 7w -12y +18

Hence, the expression in the form of equation can be simplified as:

7w - 12y + 18

The height of the flagpole will be 9.25 m to the nearest hundredth of a meter.

It is defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.

Given that, after moving a mirror with an X in the middle to a level position on the ground 8.85 metres away from the flagpole.

The top of the flagpole is then plainly indicated in the X as she moves 1.1 metres to the opposite side of the mirror. Her companion calculates that there are 1.15 metres between her eyes and the ground.

From the similarity of two triangle,

1.15 / h = 1.1 / 8.85

1.1 h = 1.15 × 8.85

1.1 h = 10.1775

h = 9.25 m

Thus, the height of the flagpole will be 9.25 m to the nearest hundredth of a meter.

The coordinates of the image of point B after the transformations is (4,3) .

What are the coordinates?

Any of a set of numbers used in specifying the location of a point on a line, on a surface, or in space latitude and longitude coordinates.

Hence, the coordinates of the image of point B after the transformations is (4,3).

The value of the first term is -8.

Here it is given that the series is in an arithmetic sequence.

The formula for the sum of a series in an arithmetic sequence.

[tex]S_{n}[/tex] = n/2( 2a + (n-1)d)

n = number of term

d = common difference

a = first term of a sequence

[tex]S_{n}[/tex]= sum of n number of terms

It is given that sum of 26 number of a term is 1417, and the sum of first 8 number of a term is 76.

So from that, we have two equations by putting the term in the equation

1417 = 26/2( 2a + (26-1)d)

1417 = 13(2a + 25d)

109 = 2a + 25d .........(1)

76 = 8/2( 2a + (8-1)d)

19 = 2a + 7d ..........(2)

Now subtract equations (1) and (2) we get

90 = 18d

d = 5

Now put the value of d in equation (2), we get

19 = 2a + 7× 5

19 - 35 = 2a

2a = -16

a = -8

Therefore the first term of the sequence is -8.

The box-and-whisker plot of the data is given below.

What is box-and-whisker plot?

When we plot a graph for the box plot, we outline a box from the first quartile to the third quartile. A vertical line that goes through the box is the median. The whiskers (small lines) go from each quartile towards the minimum or maximum value.

Given data is

12,5,22,30,7,36,14,42,15,53,25

First we will arrange it in ascending order.

5,7,12,14,15,22,25,30,36,42,53

The maximum and minimum value are 5 and 53.

First quartile is 3 and third quartile is 9

The equation in slope intercept form is [tex]\frac{x}{7} +\frac{15}{7}[/tex].

Given that the line passes through two points (-1,2) and (6,3)

Slope of the line passing through (x1,y1) and (x2,y2) is

[tex]\frac{y2-y1_ }{x_{2-x_{1} } }[/tex]

Hence slope of our line =

(3-2)/(6+1) = 1/7

So in slope intercept form the equation would be

y = 1/7 x +C

to find C

Since (-1,2) lies on the line substitute these in the line equation

2 = 1/7(-1)+c

C = 2+1/7 = 15/7

Hence equation in slope intercept form is [tex]\frac{x}{7} +\frac{15}{7}[/tex].

The slope-intercept form of a  line is one of the most common forms used to represent the equation of a line. The slope-intercept formula can be used to find the equation of a line  given the slope of the  line and the y-intercept (the y-coordinate of the point where the line intersects the y-axis). The equation of a line is an equation that is satisfied by each point  on that line.

Step-by-step explanation:

A quotient of a number and -1.5 is 21 hence it is 21 = - 1.5D and D = - 14.

An expression is a mathematical way of writing variables and constants separated by the operation of addition and subtraction. Unlike equations in expressions, we do not equate the terms to zero.

We know N = DQ + R.

Where N = The number itself, D = Divisor, Q = Quotient and,

R = Remainder.

Given, A quotient of a number and -1.5 is 21.

Let the number be D.

∴ 21 = - 1.5D

D = - 21/1.5.

The probability of putting less than 31 ounces in a cup is 0.9773.

The standard score is the number of standard deviations that a raw score deviates from or exceeds the mean of the thing being measured or observed. Standard scores are positive for raw scores above the mean and negative for raw scores below the mean.

A soft drink machine's output is normally distributed.

The mean is μ = 27 ounces per cup.

The standard deviation, σ = 2 ounces.

The z score when x is a random variable that represents the output of the machine will be given as:

Z = ( X - μ)/σ

Z = ( 31 - 27)/2

Z = 4/2

Z = 2

Then the probability of putting less than 31 ounces in a cup using the p-value from the Z table will be:

P( X < 31 ) = 0.97725

P( X < 31 ) ≈ 0.9773
