Answer:

The p-value of the test is 0.001 < 0.05, which means that there is evidence at the 0.05 level of significance that the mean one-time gift donation is greater than $70.

Step-by-step explanation:

Test if the mean one-time gift donation is greater than $70:

At the null hypothesis, we test if it is 70 or less, that is:

[tex]H_0: \mu \leq 70[/tex]

At the alternate hypothesis, we test if it is greater than 70, that is:

[tex]H_1: \mu > 70[/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 of the sample and n is the size of the sample.

70 is tested at the null hypothesis:

This means that [tex]\mu = 70[/tex]

Based on a random sample of 60 nonprofit organizations, the mean one-time gift donation in the past year was $75, with a standard deviation of $12.

This means that [tex]n = 60, X = 75, s = 12[/tex].

Test statistic:

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

[tex]t = \frac{75 - 70}{\frac{12}{\sqrt{60}}}[/tex]

[tex]t = 3.23[/tex]

P-value of the test:

The p-value of the test is the probability of finding a sample mean above 75, which is a right-tailed test with t = 3.23 and 60 - 1 = 59 degrees of freedom.

Using a t-distribution calculator, this p-value is of 0.001.

The p-value of the test is 0.001 < 0.05, which means that there is evidence at the 0.05 level of significance that the mean one-time gift donation is greater than $70.

To see the shaded regions, check out the attached image below. The shaded regions are in red.

The fractional values for each figure are:

The fractional answers are in bold. All of those fractions reduce to 1/2. Make sure that you don't reduce any of those fractions.

========================================================

Explanation:

We count out the number of squares for each figure. Then we shade half of them. For problem 1, we just shade the left half (or you can shade the right half, but you can only pick one side). This is because 3 is half of 6.

Problem 2 is a similar story, but we'll shade the first two columns out of the four total columns. You could shade the last two columns if you wanted, but you can't shade everything.

Problem 3 has an odd number of columns, but an even number of rows. I'm shading the first two rows to represent half of the blocks.

The rest are handled in a similar manner.

------------

To form the fractional results, you basically count the number of shaded smaller squares out of the number of squares total.

For example, the answer for problem 1 is 3/6 because we have 3 shaded red squares out of 6 squares total. The rest are handled the same way.

Answer:

The answer is C or the third option. "g(x) has a greater maximum value than f(x)"

Step-by-step explanation:

I took the test and got it correct.

The statement that best compares the maximum value of the two functions is g(x) has a greater maximum value than f(x).

The function f is given as:

f(x) = -2x^2 + 9

Differentiate the function

f'(x) = -4x

Set to 0

-4x = 0

Divide both sides by -4

x = 0

Substitute x = 0 in f(x)

f(0) = -2(0)^2 + 9

f(0) = 9

This means that the maximum value of function f(x) is 9

From the table of function g(x), the maximum is 11

11 is greater than 9

Hence, g(x) has a greater maximum value than f(x).

Answer:

Step-by-step explanation:

250x^3-16

2(125x^3-8)

2[(5x)^3-(2)^3]

2(5x-3)[(5x)^2+5x*3+(2)^2]

2(5x-3)(25x^2+15x+4)

==============================================

The 125 degree angle and angle 6 are supplementary. This is because of the same side interior angles theorem.

Let x be the measure of angle 6. Add this to 125, set the sum equal to 180, and solve for x.

x+125 = 180

x = 180-125

x = 55

------------

Or you could approach it this way:

y = measure of angle 2

y+125 = 180

y = 55

angle 6 = angle 2 (corresponding angles)

angle 6 = 55 degrees

-------------

Yet another way you could solve:

z = measure of angle 3

z+125 = 180

z = 55

angle 6 = angle 3 (alternate interior angles)

angle 6 = 55 degrees

A similar approach using alternate interior angles would involve angle 5 = 125, and then noticing that x+125 = 180 solves to x = 55

Answer:

The correct answer is "[tex]a+b+c=15[/tex]".

Step-by-step explanation:

The figure according to the given question is attached below.

Given that,

Number of people,

p = 4

Let the suitable notations are:

a, b, c, x, y, z and p

where,

Only leader M = x

Only champion M = y

Only range M = z

Exactly two medals = a+b+c

All three medals = p

The equations will be:

[tex]x+a+b+p=19[/tex]...(1)

[tex]y+a+c+p=27[/tex]...(2)

[tex]z+b+c+p=25[/tex]...(3)

[tex]x+y+z+a+b+c+p=48[/tex]...(4)

Now,

From equation (1), (2) and (3), we get

[tex]x+y+z+2(a+b+c)+3p=71[/tex]

[tex]x+y+z+2(a+b+c)=71-12[/tex]

[tex]x+y+z+2(a+b+c)=59[/tex]...(5)

By applying subtraction between equation (5) and (4), we get

[tex]a+b+c-p=59-48[/tex]

[tex]a+b+c=4+11[/tex]

[tex]a+b+c=15[/tex]

The five number summary you wrote out is correct.

The tip of the left whisker is at 36, since this is the smallest value and we don't have outliers. The tip of the right whisker is at 64 which is the max (we don't have outliers here either).

The left and right edges of the box are Q1 and Q3 respectively. The median is the vertical line inside the box. The vertical line does not have to be at the midpoint as the diagram shows.

The IQR (interquartile range) is found by computing IQR = Q3-Q1 = 55-39 = 16

Note that the lower fence is L = Q1 - 1.5*IQR = 39 - 1.5*16 = 15. Anything below this value of L is an outlier.

The upper fence is U = Q3 + 1.5*IQR = 55 + 1.5*16 = 113.5; anything above this value of U is an outlier. All of the values in the given set are between L and U, meaning we don't have outliers. If we had outliers, then we would have island points outside the main box-and-whisker plot.

Answer:

option A

Step-by-step explanation:

f(x) = 3x + 2

g(x) = 2x - 2

(f - g)(x) = f(x) - g(x)

           = (3x + 2) - (2x - 2)

           =3x + 2 - 2x + 2

           = x + 4

The value of function (f - g)(x) is,

⇒ (f - g)(x) = x + 4

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

Function are,

f(x) = 3x + 2 and g(x) = 2x - 2

Hence, The value of function (f - g)(x) is,

⇒ (f - g)(x) = (3x + 2) - (2x - 2)

⇒ (f - g)(x) = 3x + 2 - 2x + 2

⇒ (f - g)(x) = x + 4

Thus, The value of function (f - g)(x) is,

⇒ (f - g)(x) = x + 4
