10.3

Step-by-step explanation:

Area of triangle is : 0.5 *base * height

53 =0.5 * x * x

X =10.295

Answer: 2000/25 = 80 tiles

Step-by-step explanation:

Date: s=20

equation of surface area of a cube prism: surface area = 6s*2

the surface area to be covered with tiles is requires, the base is not included, so the equation reduces: surface area = 5s*2

subtitute values: surface area = 5(20)*2

= 5(400)

surface area = 2000

area of 2 tile is 5*2 = 25 square inches

2000/25 = 80 tiles

The measure of the amount of space occupied by a solid is called its volume.

Answer:

The first one is exponential, the second one is linear, and the last one is quadratic.

Step-by-step explanation:

The first one is exponential, because the values are increasing at an increasing rate. In other words, the difference between any consecutive x-values yield a bigger difference.

The second one is linear, because the values are increasing at a constant rate.

The last one is quadratic, because the values decrease, and then increase, which can be represented by a parabola for a quadratic equation.

Step-by-step explanation:

The average rate of change from day 2 to day 10 is given by the slope of the line m =

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

The number of houses sold on day 2 is P

The number of houses sold on day 10 is Q

Let the first point be P ( 2 , 8 )

Let the second point be Q ( 10 , 2 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 2 - 8 ) / ( 10 - 2 )

Slope m = -6/8

m = -3/4

Therefore , the number of houses sold between day 2 and 10 is -3/4 houses per day

Hence , the slope is m = -3/4 houses per day

Answer:

The p-value is 0.1228.

Step-by-step explanation:

Before testing the hypothesis, we need to find the sample mean and the standard deviation.

Sample of 13:

The sample mean is the sum of all values divided by 13. Using a calculator, it is: X = 28.15.

The sample standard deviation is the square root of the division of the sum of the differences squared between each value and the mean, by the number of values. Using a calculator, we get s = 4.0162.

A researcher wants to test whether the average gas mileage of this type of car is different from 30 mpg.

At the null hypothesis, we test if the average gas mileage is of 30 mpg, that is:

[tex]H_0: \mu = 30[/tex]

At the alternate hypothesis, we test if the average is different from 30, that is:

[tex]H_1: \mu \neq 30[/tex]

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.

30 is tested at the null hypothesis:

This means that [tex]\mu = 30[/tex]

From the sample:

[tex]X = 28.15, s = 4.0162[/tex].

Value of the test-statistic:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{28.15 - 30}{\frac{4.0162}{\sqrt{13}}}[/tex]

[tex]t = -1.66[/tex]

P-value of the test:

The p-value of the test is the probability that the sample mean differs from 30 by at least |28.15 - 30| = 1.75, which is a two-tailed test with t = -1.66 and 13 - 1 = 12 df.

Using a t-distribution calculator, this p-value is 0.1228.

slope=0

Answer:

Lesley purchased 1 oval bead and 4 round beands.

Step-by-step explanation:

Given that Lesley purchased 5 beads at a total cost of 80 cents, and the round beads cost 15 cents each, and the oval beads cost 20 each, to determine what are the numbers of round and oval beads Kelsey purchased, the following calculation must be performed :

5 x 0.20 + 0 x 0.15 = 1

4 x 0.20 + 1 x 0.15 = 0.95

2 x 0.20 + 3 x 0.15 = 0.85

1 x 0.20 + 4 x 0.15 = 0.80

Therefore, Lesley purchased 1 oval bead and 4 round beands.

[tex]f(x) = 32(0.8)^x[/tex]

[tex]g(x) = 25(0.8)^x[/tex]

Required

A function that represents the total resale value of the two vehicles

To do this, we simply add up the functions

[tex]h(x) = f(x) + g(x)[/tex]

[tex]h(x) = 32(0.8)^x + 25(0.8)^x[/tex]

Factorize

[tex]h(x) = (32 + 25)(0.8)^x[/tex]

[tex]h(x) = 57(0.8)^x[/tex]

Ok so when a parenthesee or this symbol ( is beside a letter/Number, in this case 5 you multiply it by whats inside, so 5x10.5, and 5x10.5=52.5. Now for S, it would be 52.5+S.
