Write the answer in scientific notation and in standard form.Round to the appropriate number of significant digits.

Aleks [24]

Hey there, the answer is C.

After multiplying, you will get .37278. However, it's asking you to consider the significant figure of 3 so you'll have to round it to .373. C has that only option

McAllister et al. (2012) compared varsity football and hockey players with varsity athletes from noncontact sports to determine

jonny [76]

Answer:

$t _{critical} = 1.760$

t = 2.2450

d. 0.264

Step-by-step explanation:

The null hypothesis is:

$H_o: \mu_1 - \mu_2 = 0$

Alternative hypothesis;

$H_a : \mu_1 - \mu_2 > 0\\$

The pooled variance t-Test would have been determined if the population variance are the same.

$S_p^2 = \dfrac{(n_1-1)S_1^2+(n_2-1)S^2_2}{(n_1-1)+(n_2-1)}$

$S_p^2 = \dfrac{(8-1)2.507^2+(8-1)2.8282^2}{(8-1)+(8-1)}$

$S_p^2 = 7.14$

The t-test statistics can be computed as:

$t= \dfrac{(x_1-x_2)-(\mu_1 - \mu_2)}{\sqrt{Sp^2 ( \dfrac{1}{n} +\dfrac{1}{n_2})}}$

$t= \dfrac{(9-6)-0}{\sqrt{7.14 ( \dfrac{1}{8} +\dfrac{1}{8})}}$

$t= \dfrac{3}{1.336}$

t = 2.2450

Degree of freedom $df = (n_1 -1) + ( n_2 +1 )$

df = (8-1)+(8-1)

df = 7 + 7

df = 14

At df = 14 and ∝ = 0.05;

$t _{critical} = 1.760$

Decision Rule: To reject the null hypothesis if the t-test is greater than the critical value.

Conclusion: We reject $H_o$ and there is sufficient evidence to conclude that the test scores for contact address s less than Noncontact athletes.

To calculate r²

The percentage of the variance is;

$r^2 = \dfrac{t^2}{t^2 + df}$

$r^2 = \dfrac{2.2450^2}{2.2450^2 + 14}$

$r^2 = \dfrac{5.040025}{5.040025+ 14}$

$r^2 = 0.2647$

Translate the sentence into an inequality. The sum of 3 and c is less than -29.

Solnce55 [7]

Answer:

3+c < -29 or c+3 < -29 because of communitive property

Step-by-step explanation:

First, the sum means addition, you could write 3+c or c+3 because addition is communitive property.

Then the sum is less than -29 so we need to use the less than symbol which is this symbol: <

Now write the inequality! 3+c < -29

A high school club has a performance, with 800 tickets to sell. Tickets are $6 before the day of the show, and $9 on the day of

sweet-ann [11.9K]

A) Let x = number of presale tickets
y = number of day of show tickets 

x + y =< 800 
6x + 9y >= 5000 

b) 6x + 9y >=5000 
6(440) + 9y >=5000 

y >= 262.2 
263 tickets 

440 advance purchase tickets added to 263 day of show tickets is 703 tickets, which is below the 800 ticket maximum.
