Answer:

1) H0: μ₁=μ₂ against the claim Ha: μ₁ ≠μ₂

2)The test statistic is

t= x1`-x2`/ Sp √ ( 1/n₁ + 1/n₂)

where

Sp=  s₁² ( n1-1) + s₂²(n2-1) /(n1-1) + (n2-1)

3) D.f= n1+n2-2= 32+28-2= 58

Step-by-step explanation:

The null hypothesis is that there is no  difference in population means (masterâs degree minus bachelorâs degree)

The claim is that there there is a difference in population means (masterâs degree minus bachelorâs degree)

1) H0: μ₁=μ₂ against the claim Ha: μ₁ ≠μ₂

2)The test statistic is

t= x1`-x2`/ Sp √ ( 1/n₁ + 1/n₂)

where

Sp=  s₁² ( n1-1) + s₂²(n2-1) /(n1-1) + (n2-1)

Putting the values

Sp= 12,250,000( 31)  + 16,000,000(27)/ 31+27

Sp=  379,750,000- 432,000,000/58

Sp= -52,250,000/58

Sp= -900,862.1

Now Putting the values in the t- test

t= x1`-x2`/ Sp √ ( 1/n₁ + 1/n₂)

t= 55,000- 58,000/ -900,862.1 √1/32+ 1/28)

t= -3000/ -233,120.21

t= 0.012868

3) D.f= n1+n2-2= 32+28-2= 58

for 2 tailed test the critical value of t is obtained by

t≥ t∝/2 ( d.f)=t≥ t0.025 (58)= ± 2.0017

4) Since the calculated value of t=  0.012868 does not fall in the critical region t≥ t∝/2 ( d.f)= ± 2.0017 we conclude that H0 is true and accept the null hypothesis.

Answer:

1) D: none of them

2) C: ae^(ax)

3) A: cot x

4) A: (3,0)

Step-by-step explanation:

1) the degree of the denominator is more than that of the numerator, thus as n approaches infinity, the function would approach zero. The answer is not available among the options

2) y = e^(ax)

dy/dx = ae^(ax)

3) y = log(sin x)

dy/dx = (1/sin x) × d(sin x)/dx

dy/dx = cosx/sin x

dy/dx = 1/(sin x/cos x)

We know from trigonometry that sin x/cos x = tan x. Thus

dy/dx = 1/tan x

dy/dx = cot x

4) An inflection point is usually the point where the second derivative is equal to zero.

f(x) = x³ - 9x²

f'(x) = 3x² - 18x

f"(x) = 6x - 18

Equating to zero gives;

6x - 18 = 0

x = 18/6

x = 3

Thus the inflection point is (3,0)

Answer:

y = 1x + 2

Step-by-step explanation:

y = 3, x = 1

=> 3 = 1 x 1 + ?

=> 3 = 1 + ?

=> ? = 2

Try again:

y = 4, x = 2

=> 4 = 1 x 2 + ?

=> 4 = 2 + ?

=> ? = 2 (correct)

- So, the equation will be: y = 1x + 2

There are no parentheses:

Do exponent:

1/2 (16) – 6

Then multiplication and division in the order that they come in:

8 – 6

Then addition and subtraction in the order that they come in:

Answer:

y = -3x + 7

Step-by-step explanation:

Points on the graph: (0, 7) and (3, -2)

Slope:

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

m=(-2-7)/(3-0)

m=(-9)/3

m = -3

Slope-intercept:

y - y1 = m(x - x1)

y - 7 = -3(x - 0)

y - 7 = -3x

y = -3x + 7

Answer:

0 on the x axis and -6 on the y axis i think

Answer:

It would be located on the Y-axis

Step-by-step explanation:

If you plot 0,-6 on a graph, you start on the origin since the x-axis is 0, and for the -6, you go DOWN 6 units, which is on the Y-axis. Therefore, the answer the y-axis.

Answer:

B. 40.2 degrees

Step-by-step explanation:

Consider ΔFGE. Given that ∠FEG = 90° and ∠FGE is x°.

To find the value of ∠FGE use trigonometric ratios.

Use sine ratio to find the value of ∠FGE.

Rewriting it in terms of x° as follows,

Now find the opposite and hypotenuse side of the angle ∠FGE.

So opposite side of ∠FGE is FE and hypotenuse side of ∠FGE is FG.

Substituting the values,

Given that length of FE is 12 inch and FG is 18.6 inch.

Substituting the value,

To find the value of x, taking inverse sin.

Calculating the value,

Rounding to nearest tenth the value of angle is 40.2

Therefore measure of ∠FGE is 40.2° .

Step-by-step explanation:

mark me brainlest

Answer:

Step-by-step explanation:

From the given information:

(i)

The domain includes all runners in a race.

x is "R" y if x beats y

Now, in a race; either x beats y or y beats x

So, x"R"y or y "R" x, but here at least two runners tied.

Thus, the relation is not in total order as x"R"y or y"R"x may not happen.

(j)

S = {a,b,c,d}

The domain = Power set of S

x"R"y if |X| ≤ |Y|

Thus, the relation is a partial order.

(k)

S = {a,b,c,d}

The domain = Power set of S

x"R"y if |X| ≤ |Y|

Answer:

B. 0, 1, 2, 3

Step-by-step explanation:

If n were to be 4, the expression would then be incorrect because 36 is not greater than itself. However, if n was 0, 1, 2, or 3, each value would be less than 36, which is what we are looking for.

36 > 9n

36 > 9(0)

36 > 0

Correct!

36 > 9n

36 > 9(1)

36 > 9

Correct!

36 > 9n

36 > 9(2)

36 > 18

Correct!

36 > 9n

36 > 9(3)

36 > 27

Correct!

36 > 9n

36 > 9(4)

36 > 36

Incorrect! This expression would only be correct if the sign was representative of greater than or equal to, rather than just equal to.

I hope this made sense! Have an amazing day. :)

Answer:

0.0082 = 0.82% probability that a randomly selected person will wait more than 42 seconds.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean wait time of 30 seconds and a population standard deviation of 5 seconds.

This means that [tex]\mu = 30, \sigma = 5[/tex]

What is the probability that a randomly selected person will wait more than 42 seconds?

This is 1 subtracted by the pvalue of Z when X = 42. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{42 - 30}{5}[/tex]

[tex]Z = 2.4[/tex]

[tex]Z = 2.4[/tex] has a pvalue of 0.9918

1 - 0.9918 = 0.0082

0.0082 = 0.82% probability that a randomly selected person will wait more than 42 seconds.

Answer:

44

Step-by-step explanation:

Refer to PEMDAS.

5 x 4 = 20

5 x 10 = 50

20 - 16 = 4

4 + 50 = 54

54 - 10 = 44

Answer:

2. Simplify  3+9  to  12.

6x=12

3. Divide both sides by 6.

x=12/6

4.

Simplify 12/6 to 2

x = 2
