Answer:

Cost of per session the average rate is $45.

Step-by-step explanation:

It is given that a gym membership with two personal training session cost $125, while gym membership with five personal training sessions cost $260.

It is required to find what is the cost per session.

Step 1 of 1

It is given that a gym membership with two personal training session cost $125, while gym membership with five personal training sessions cost $260.

To find the cost of per session calculate the average rate.

Now let $f(x)$ be the cost per session use the for the average rate of change, and the input value is the number of personal traings x.

[tex]$m=\frac{f\left(x_{2}\right)-f\left(x_{1}\right)}{x_{2}-x_{1}}$$[/tex]

Now substitute, $125 for [tex]$f\left(x_{2}\right)[/tex], 260 for [tex]$f\left(x_{1}\right), 2$[/tex] for [tex]$x_{1}$[/tex] and 5 for [tex]$x_{2}$[/tex] then,

Cost of per session the average rate is $45.

Answer:

y=-3x-2

Step-by-step explanation:

The slope-intercept form is y=mx+b

where m is slope and b is y-intercept.

Substitute m=-3 and point (x,y)=(1,-5) into the equation:

-5=-3(1)+b

-5=-3+b

b=-5-(-3)=-5+3=-2

Therefore, the required equation:

y=-3x-2

Part B) D

Step-by-step explanation:

Total sweets = 10

Red = 4

Green = 2

Yellow = 3

Purple = 1

A = 2/10 = 1/5

B = 3/10

C = 4/10 = 2/5

D = 1

Yellow sweets = 3

Total = 10

Probability = yellow/total

Hence, B shows the probability of showing a yellow sweet.

Sweets that are not orange = 10 (All sweets are not orange)

Total = 10

Probability = sweets that are not orange / total

Probability = 10 / 10

Hence, D shows the probability of choosing a sweet that is not orange.

Answer:

A. 36

Step-by-step explanation:

Because the two angles at the bottom of both the triangles are congruent, the two triangles are similar. Therefore, the corresponding side lengths of the triangles must be proportional to each other

if the area of a triangle is hb/2,

(with h=length of height, b=length of base)

the height of the first triangle is:

25 = 10h/2

50 = 10h

h=5

you can write ratios representing the proportions of the two triangles:

5/x = 10/12 (with x=height of second triangle)

x=6

then find the area of the second triangle with the height (6) and base (12)

(6*12)/2 = 36

Answer:

150 square feet

Step-by-step explanation:

Method 1: The area of a trapezoid is

Method 2: You can also split it into a rectangle and a triangle.

12 x 8 + 12 x (17 - 8)/2 = 150 square feet

The slope of the given containing ordered paid A(2,-5) and B(-2,6) is -11/4.

A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

Answer:

(i) -34° C.
(ii) The temperature had fallen by 11° C.

Step-by-step explanation:

(i) As it's a negative number its like we are adding it so 23 + 11 = 34 and as it is a negative number it would be -23 - 11 = -34 which makes it -34° C.

(ii) We know that the temperature now is -45° C, we need to find out how much the temperature had fallen in the 4 hours which had passed. So what we do is essentially add it considering its a negative number so we add -34 by 11 which equals -45. We do this so we can find out how much the temperature had dropped within the 4 hours and as we know that we needed to add 11 to the previous temperature (-34° C) it means that the temperature has dropped by 11° C.

[tex]A = \frac{\sqrt{3} }{4} *S^2[/tex]

Replacing what we know in the area formula:

140 = 2(L + 10) + 2L

140 = 2L + 20 + 2L

Suppose that a probability is approximated to be zero based on empirical results, this does not mean that the event is​ impossible.

The likelihood that an event will occur is defined by probability. There are many instances in real life where we may need to make predictions about how something will turn out. The outcome of an event may be known to us or unknown to us.

By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.

There could be 0, 2, or 4 complex solutions

Step-by-step explanation:

The Fundamental Theorem of Algebra states that any polynomial with n degree will have n solutions So since the degree of the polynomial you provided has a degree of 4, that means there are 4 possible solutions. This question specifically asks for complex zeroes. Complex zeroes come in conjugate pairs, so that means if you have one complex zero, there is another complex zero which is it's conjugate. For this reason, there can only be an even number of complex zeroes. And since there's 4 possible solutions, There could be 0, 2, or 4 complex solutions
