BRAINLIEST WILL GIVE

Answer:

Hо:p = 0.35

H1:p > 0.35

Step-by-step explanation:

The magazine wants to check if the the proportion of readers interested in the online edition is equal to 35% (0.35) or greater than 35% (>0.35). Denote by p, the proportion of readers interested in the online edition. Then the null hypothesis,the hypothesis that contains equal-to sign- will be Hо:p = 0.35 and the alternative hypothesis will be H1:p > 0.35.

Answer:

4.5

Step-by-step explanation:

Probably too late for your RSM homework, but here is the solution:

6/(9-x) [Time they motored upstream] +6/x [Time it took the bottle to get back to the starting point] = 8/3 [Total Time]

Simplify to 54/(x(9-x))=8/3

Cross multiply: 162=(8x)(9-x)

Simplify -x^2+9x=20.25

Multiply both sides by negative one and move 20.25 to the other side. x^2-9x+20.25=0

Solve and get 4.5 :D!

Answer:

Amount = $3.84

Step-by-step explanation:

Given the following data;

Total bill = $48

Tip = 8%

To find the amount of dollars tipped?

[tex] Amount = \frac {8}{100} * 48[/tex]

[tex] Amount = \frac {384}{100} [/tex]

Amount = $3.84

Therefore, the amount of dollars Mr. Cosgrove tipped is $3.84.

Solution :

It is given that P(x) is said to be complete or proper probability distribution if it satisfies the following two ways :

1. [tex]$P(x) \geq 0$[/tex]

2. [tex]$\sum_z P(x) = 1$[/tex]

Now consider,

[tex]$\sum_z P(x) = 1$[/tex]

⇒ [tex]$P(x=0)+P(x=1)+P(x=2)+P(x=3)+P(x=4)+P(x=5)=1$[/tex]

⇒ [tex]$0.61+T+0.14+0.01+0.01+0.03=1$[/tex]

⇒ [tex]$0.8+T=1$[/tex]

⇒ [tex]$T=1-0.8$[/tex]

       = 0.2

Therefore, the value of T is 0.2

Thus, option (c) is correct.

Answer:

113.08 cm^3

Volume for sphere = 4/3 Pi 3^3

y = x^2 - (x+0) (x+0)< 3 would equal x = 1.25 and y = 2.5 max

then y = 9 and x = 0 around the y axis

We find (1.25, 2.5) (0,9)

y + 1 = 0 + 1.25 + 9

y+ 1 = 10.25

radius therefore = 3^2 = 3

and surface area = pi x 9 =  28.2743338823

= 28.27cm^2 x 4 = 113.1cm

If it is a sphere you then multiple 4/3 pi r^3 is exactly the same as 4pir^2

Step-by-step explanation:

The volume of the solid is [tex]9\pi[/tex] cubic unit.

The volume of the solid obtained by rotating the curve [tex]y=f(x)[/tex] is given as,

                        [tex]V=\int\limits^b_a \pi {y^{2} } \, dx[/tex]

Given that, [tex]y=x^{2} ,a=0,b=3[/tex]

Substitute above values in volume formula.

         [tex]V=\int\limits^3_0 \pi{x^{2} } \, dx \\\\V=\pi(\frac{x^{3} }{3} )^{3} _{0}\\\\V=\frac{\pi}{3} (27-0)=9\pi[/tex]

Thus, the volume of the solid is [tex]9\pi[/tex] cubic unit.

Answer:

A=2(wl+hl+hw)

Step-by-step explanation:

Answer:

a) Interpret the results and determine whether or not the coefficients are significantly dif- ferent fromzero. Do the coefficients have the expected sign?

An increase in reputation by one category, increases the cost by

roughly $3,985. The larger the size of the college/university, the

lower the cost. An increase of 10,000 students results in a $2,000

lower cost. Private schools charge roughly $8,406 more than public

schools. A school with a religious affiliation is approximately $2,376

cheaper, presumably due to subsidies, and a liberal arts college also

charges roughly $416 less. There are no observations close to the

origin, so there is no direct interpretation of the intercept. Other than

perhaps the coefficient on liberal arts colleges, all coefficients have

the expected sign.

(b) What is the forecasted cost for a liberal arts college, which has no religious affiliation, a size of 1,500 students and a reputation level of 4.5? (All liberal arts colleges are private.)

7,311.17 + 3,985.20×4.5 – 0.20×1500

+ 8,406.79×1 – 416.38×1 – 2,376.51×0=$ 32,935

(c) Suppose that you switch from a private university to a public university, which has a ranking tha's 0.5 lower and 10,000 more students. What is the effect on your cost?

Roughly $ 12,400. Since over the four years of education, this

implies approximately $50,000, it is a substantial amount of money

for the average household.

(d) What is the p-value for the null hypothesis that the coefficient on Size is equal to zero? Based on this, should you eliminate the variable from the regression? Why or why not?

Using a one-sided alternative hypothesis, the p-value is 6.2 percent. Variables should not be eliminated simply on grounds of a statistical test. The sign of the coefficient is as expected, and its magnitude makes it important. It is best to leave the variable in the regression and let the reader decide whether or not this is convincing evidence that the size of the university matters

(e) You want to test simultaneously the hypotheses ha and bert - 0. Your regression package returns an F-statistic of 1.23. Can you reject the null hypothesis?

The critical value for F2,∞ is 3.00 (5% level) and 4.61 (1% level). Hence you cannot reject the null hypothesis in this case

(f) Eliminating the Size and Dlibartvariables from your regression, the estimated regression becomes 5,450.35+3,538.84 .

Step-by-step explanation:

a.An increase in reputation by one category, increases the cost by

roughly $3,985. The larger the size of the college/university, the

lower the cost. An increase of 10,000 students results in a $2,000

Answer:

B. Decreasing; The slope of the line between points D and E is negative

Step-by-step explanation:

The graph clearly shows that the speed is decreasing between these points. This narrows down your options to either Option B or Option D. A completely vertical line has a slope of undefined. The line is not completely vertical and undefined, so Option D is incorrect. This leaves B as correct. A negative slope is a line rising right to left.
