I NEED HELP PLEASEEE!!!! I HAVE BEEN WORKING ALL DAY

See attached screenshot

:)

Reason:

There is only one Z distribution, which is also known as the standard normal distribution. This distribution has a mean of mu = 0 and a standard deviation of sigma = 1. So unless you consider a family to only have one member, then I'd consider the statement your teacher gave you to be false.

On the other hand, if we were talking about the student T distribution, then this is a family of function curves. The reason being is that the degrees of freedom (df) will change the shape of said curve. The value of df will depend on the sample size n. Recall that df = n-1. As n gets larger, then the T distribution curves will slowly start to look like the Z distribution. For n > 30, the difference is so very minor that it's easier to swap over to the Z distribution even if you don't know sigma.

In other words, there is a family of T distribution curves in which slowly approach to mimicking the Z distribution curve when n is large (usually n > 30).

Question #10

Answer:

B. False

Step-by-step explanation:

This graph is not a function. The graph fails the Vertical Line Test.

Answer:

no

Step-by-step explanation:

plug 6 in for x and 2 in for y, as (x, y) = (6, 2)

first equation:

y = 1 * y

2(6) + 1(2) = 10

12 + 2 = 10

14 = 10

this is false

second equation:

3(6) + 2(2) = 10

18 + 4 = 10

22 = 10

this is false

for this to be a solution, it must fit into both equations. as this fits into neither, this is not a solution

To find the surface area of a rectangular prism, we can use the following formula:

[tex]SA=2(lw+lh+wh)[/tex]

We're given:

Plug the given measurements into the formula for surface area:

[tex]SA=2(lw+lh+wh)\\SA=2[(4)(1)+(4)(3)+(1)(3)]\\SA=2(4+12+3)\\SA=2(19)\\SA=38[/tex]

Therefore, the surface area of the rectangular prism is 38 yd².

38 square yards

Since the figure is a triangle, we must use the triangle area formula to solve the problem, which is [tex]A = \frac{1}{2} b h[/tex]. By using this formula, we can plug in the numbers shown. Then, we can multiply.

[tex]A = \frac{1}{2} * 5 *22[/tex]

[tex]A = \frac{1}{2} * 110[/tex]

[tex]A = 55^2[/tex]

The area of the triangle is 55 yards squared.

Step-by-step explanation:

5% = .05

N = 700 000 (1+.05)^t

radius= 12 cm

circumference and area of the circle.

[tex]c = 2\pi \: r[/tex]

[tex]c = 2 \times \pi \times 12[/tex]

[tex]c = 75.39822 \: cm[/tex]

[tex]c = 75.4 \: cm[/tex]

[tex]a = \pi {r}^{2} [/tex]

[tex]a = \pi \times {12}^{2} [/tex]

[tex]a = 452.38934 \: {cm}^{2} [/tex]

[tex]a = 452.39 \: {cm}^{2} [/tex]

Direct proportional relationship formula

Given values

Find the value of k using the formula

The equation for this case is

Find the value of y when x = 5

Answer:

A.  y = 9.8x

B.  49 newtons

Step-by-step explanation:

Part A

Definition of the given variables:

If the gravitational force is directly proportional to the mass, then:

   [tex]y \propto x \implies y=kx \quad \textsf{(for some constant k)}[/tex]

Given:

Substitute the given values into the equation and solve for k:

[tex]\implies 19.6=2k[/tex]

[tex]\implies k = 9.8[/tex]

Therefore, the direct variation equation is:  [tex]y=9.8x[/tex]

Part B

To find the gravitational force of an object with mass of 5 kg, substitute x = 5 into the found equation from part A and solve for y:

[tex]\implies y=9.8(5)[/tex]

[tex]\implies y=49\:\: \sf newtons[/tex]

Answer:

1.  Slope = 1

2. Slope = 3

3. Slope = -2

4. Slope = 2

Step-by-step explanation:

Okay so when we are finding the slope of two points we use the slope formula

[tex]slope = \frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

Let me know if anything is unreadable !

Answer:

NO

Step-by-step explanation:

They are not bc they are rotated and theyfore not the same exatly. The are similar NOT congruent.

Answer:

As [tex]x[/tex] approaches infinity [tex]f(x)[/tex] approaches negative infinity.

Step-by-step explanation:

As you can see in the graph as [tex]x[/tex] grows larger in the negative direction, the [tex]y[/tex] increases in the negative direction too.

Thus:

[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]

Answer: C. As the number of trials gets larger, the average of the trials approaches the expected value

Step-by-step explanation:

The expected value is the weighted average of the results of an experiment. As more trials go on, the actual average is more likely to get closer to the expected value. The expected value can be explained as the theoretical result after infinity trials, so as the number of trials approaches infinity, the result will approach the expected value.

Answer:

$2728

Step-by-step explanation:

Use compound interest formula:

[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]

P = 1700, r = 0.03, n = 1, t = 16

Plug in numbers:

[tex]A = 1700(1 + \frac{0.03}{1})^{(1)(16)}[/tex]

Simplify:

[tex]A = 1700(1.3)^{16[/tex]

Use calculator:

[tex]A = 2728[/tex]
