Answer:
2.71
Step-by-step explanation:
Using this formula: Volume= 4 over 3 * π * r cubed.
then do R=(3V4π)⅓=(3·83.54·π)⅓≈2.71144
2.71144 rounded to the nearest 10 is 2.71

Sophia, a yoga instructor at Yoga for You, selected random samples of 210 students from a nearby high school and 210 students from a nearby college to compare levels of physical fitness. The mean and standard deviation of the fitness levels of the high school students were 82 and 14 respectively. The mean and standard deviation of the fitness levels of the college students were 86 and 17 respectively. She conducted a two-sided t-test with a resulting t-value of 2. 63. Lf a = 0. 05, what is an appropriate conclusion from this study?
Because the sample means only differ by four, the population means are not significantly different.
Because the second group has a larger standard deviation, their mean fitness score is significantly higher.
Because the second group has a larger standard deviation, the mean fitness score of the first group is significantly higher
Because the p-value is greater than a 0. 05, the mean fitness scores for the two groups of students are not significantly different.
Because the p-value is less than a 0. 05, the mean fitness scores for the two groups of students are significantly different
Because the p-value is less than 0.05, the mean fitness scores for the two groups of students are significantly different
========================================================
Explanation:
Use a T calculator to find that P(T > 2.63) = 0.00459 approximately when we have 209 degrees of freedom.
Double this to get 2*0.00459 = 0.00918 and this is the approximate p-value
Since the p-value is less than alpha = 0.05, this means we reject the null and conclude that the two population means are significantly different.
Santa seated his guests so that X number of people sat at each of Y number of tables. Mrs. Claus placed Y number of people at each table, but she had X number of tables. Compare the number of guests Santa and Mrs. Claus were able to seat.
Answer:
they are the same
Step-by-step explanation:
The number of guests seated were, in each case, ...
(guests per table) × (number of tables)
__
For Santa, this product is ...
X × Y
For Mrs. Claus, this product is ...
Y × X
The commutative property of multiplication tells you that ...
XY = YX
The numbers of guests were the same.

Solve the following ⇒ 8x-5=5(x-4)
Answer:
x = -5
Step-by-step explanation:
Given:
[tex]\displaystyle \large{8x-5=5(x-4)}[/tex]
Distribute 5(x-4):
[tex]\displaystyle \large{8x-5=5x-20}[/tex]
Add both sides by 5:
[tex]\displaystyle \large{8x-5+5=5x-20+5}\\\displaystyle \large{8x=5x-15}[/tex]
Subtract both sides by 5x:
[tex]\displaystyle \large{8x-5x=5x-15-5x}\\\displaystyle \large{3x=-15}[/tex]
Divide both sides by 3:
[tex]\displaystyle \large{\dfrac{3x}{3}=\dfrac{-15}{3}}\\\displaystyle \large{x=-5}[/tex]
Therefore, your solution is x = -5
Answer:
x = -5
Step-by-step explanation:
8x - 5 = 5(x - 4)Distributing the value in the RHS
5(x - 4)5(x) - 5(4)5x - 20Equating to the RHS
8x - 5 = 5x - 20Bring x terms to the left and numbers to the right.
8x - 5x = -20 + 53x = -15Divide both sides by 3.
3x/3 = -15/3x = -5Which sign completes each expression?

Max went to a shopping mall with $35 in his wallet. He spent two fifths of the money he had in his wallet at the bookstore. How much money, in dollars, did he have left?
$21
$26
$10
$13
Answer:
$21
Step-by-step explanation:
1) Find the amount spent.
"Two fifths" = 2/5
So, he spent 2/5 of 35.
= 2 x 35 / 5
= 70 / 5
= 14
2) Subtract 14 from 35, since 35 is the total amount of money he had.
= 35 - 14
= 21
Answer:
$21
Step-by-step explanation:
Given that:
Max went to a shopping mall with $35 in his wallet.
He spent two fifths of the money he had in his wallet at the bookstore.
To Find:
How much money, in dollars, did he have left?
Solution:
Let the left money that max have = x
Base on the given:
$35-(2/5)×$35=x
⇒ $35-($2×7)=x
⇒ $35-$14=x
⇒ x=$21
Hence, max has $21 left.

Step-by-step explanation:
find the area of the circle.
diameter=8 inches
Answer:
Area = 32 π in^2
Step-by-step explanation:
Area of the Circle : Area = 2 *π * r^2
diameter = 2 *radius
8 inches = 2 * radius
radius = 8 in/2 = 4 in
radius = 4 in
Area = 2 *π * r^2
Area = 2 *π * (4 in)^2
Area = 2 *π * 16 in^2
Area = 32 π in^2
