Step-by-step explanation:

Given

[tex]C = (-4,1)[/tex]

[tex]D = (3,3)[/tex]

[tex]m : n =5:2[/tex]

Required

The y coordinate

When a line is divided into segments, by ratios.

The formula is:

[tex](x,y) = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})[/tex]

By comparison:

[tex]y = \frac{my_2 + ny_1}{m + n}[/tex]

Where:

[tex]y_1 = 1; y_2 = 3[/tex]

[tex]m : n =5:2[/tex]

So, we have:

[tex]y = \frac{5*3 + 2*1}{5 + 2}[/tex]

[tex]y = \frac{15 + 2}{7}[/tex]

[tex]y = \frac{17}{7}[/tex]

Answer:

4.16%

Step-by-step explanation:

Had it on my test gl!

The probability that a new battery will last between 7 and 8 years is 4.16%.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

We have,

µ = 5 years and σ = 1.2

Now, P( 7 < x <8)

= P ( 7- µ/σ <  x- µ/σ < 8- µ/σ)

= P( 7- 5/1.2 < 7- µ/σ < 8- 5/1.2)

= P (1.5 < z < 2.5)

= Φ(2.5) - Φ (1.5)

= 0.9938 - 0.9522

= 4.16%

Answer:

The answer is B. [tex]\frac{6}{5}[/tex].

Step-by-step explanation:

In order to solve for the length of the altitude of the smaller pyramid, start by writing the length of the altitudes and the length of the pyramids in a proportion. The proportion should look like [tex]\frac{3}{5}[/tex] = [tex]\frac{x}{2}[/tex] because each number has to correspond with its similar number.

Next, cross multiply both fractions to get an equation, which will look like   5x=(3)(2). Simplify the equation, and now it will look like 5x=6.

Then, divide both sides by 5, and the final answer will be [tex]\frac{6}{5}[/tex].

Answer: $1,540.00 is the total amount needed for the class trip

Step-by-step explanation:

Data: $110.00 earned for class trip

14th of the money needed

Money needed: x

Step one, Make the equation

110x14=x

Reason: Since we know 110.00 is a 14th of the money needed, we know multipling it by 14 will get us the money needed for the class trip. Having it in an equation will make it easier to solve.

Step two, Evaluate the equation

110x14=x=1540=x

Reason: The only thing that was left to do was to multiply 110 by 14 to get 1540 since the x was already isolated to begin with. That leaves us with the  answer of x=1540.

However, since this is a real world problem, we have to make the answer more realistic so the final answer is '$1,540.00 is the total amount needed for the class trip'

Answer:

81

Step-by-step explanation:

Range = maximum - minimum so here, we'd have:

52 = max - 29

Add 29 to both sides to solve.

The highest score if the range is 52 and the lowest score is 29 is 81.

Range is the difference between the highest and lowest values of a set of observations. Range is a measure of variation.

Range = highest value - lowest value

Highest score = range + lowest score

52 + 29 = 81

Answer:

D.

Step-by-step explanation:

Answer:

49.12 in²

Step-by-step explanation:

The composite figure here is a semicircle and a triangle :

Area of triangle = 1/2 * base * height

Base of triangle = 8 inches ; height = 6 inches

Area of triangle = 1/2 * 8 * 6 = 48/2 = 24 in²

Area of semicircle = 1/2 * πr²

Radius = 4 in

Area of semicircle = 1/2 * 3.14 * 4² = 25.12 in²

Area of composite figure :

Area of triangle + Area of semicircle

(24 in² + 25.12 in²)

= 49.12 in²

Answer:

Part a:  Since the calculated value of t = 2.412 does not fall in the critical region t > ± 2.539 we conclude that population mean expense ratio does not exceed 1% at 0.01 significance level.

Part b:  Yes we accepted the null hypothesis when it is false so we made a type II error.

Part c: Power = 0.6591=0.66

Step-by-step explanation:

Part a:

Let the null and alternate hypotheses be

H0: u ≤ 1 against the claim Ha: u > 1

The significance level is ∝=0.01

As the standard deviation of the population is not given we use t- test which has n-1= 20-1= 19 degrees of freedom

This is one tailed test the critical region is t > ± 2.539

The mean is calculated to be 1.24 and standard deviation of the sample = s= 0.4486

We take population mean = u= 1

The test statistic is

t = x`-u/ s/ √n

t= 1.24-1 / 0.445/√20

t= 0.24/0.0995

t= 2.412

Since the calculated value of t = 2.412 does not fall in the critical region t > ± 2.539 we conclude that population mean expense ratio does not exceed 1% at 0.01 significance level.

Part b:

Type I errors are those errors when the null hypothesis is true and is rejected.

Type II errors are those in which the null hypothesis is false and is accepted.

If we had rejected the null hypothesis as it was true then we would have made a type I error.

Population mean = u = 1.33

And our null hypothesis is u= 1

Yes we accepted the null hypothesis when it is false so we made a type II error.

Part c:

When σ= 0.5

For Part a: μ= 1.33

Power = P (reject H0/ H0 is false)

= 1-β

P (reject H0/ H0 is false) = P (z > 2.539+ (u`-u0) / σ*√n)

= P (z > 2.539+ (1-1.33) /0.5 *√20)

=P (z > 2.539-2.9516)

= P (z > 0.4126)

= 0.5 - P (z= 0.2938)                                         from the area of table.

= 0.5- 0.1591

=0.3409

Power = 1-β = 1- 0.3409= 0.6591=0.66
