Answer:
Step-by-step explanation:
The null and the alternative can be computed as:
[tex]H_o : \mu = 7.62[/tex]
[tex]H_1 : \mu < 7.62[/tex]
[tex]Claim: \mu < 7.62[/tex]
[tex]\alpha= 0.05[/tex]
The critical value for a left-tailed test at [tex]\alpha= 0.05[/tex] = -1.645
The test statistics can be computed as:
[tex]Z = \dfrac{\overline x - \mu}{\dfrac{\sigma}{\sqrt{n}} }[/tex]
[tex]Z = \dfrac{6.78 - 7.62}{\dfrac{1.77}{\sqrt{54}} }[/tex]
[tex]Z = -3.487[/tex]
The P-value = (Z< -3.487)
The P-value = 0.00024
Decision Rule: TO reject [tex]\mathbf{H_o}[/tex] at [tex]\alpha= 0.05[/tex], if test statistics is less than the critical value (left tailed)
Conclusion: We reject [tex]\mathbf{H_o}[/tex] at ∝ = 5%, thus there is enough evidence to support the claim that the college students average daily ownership expenses are less than the national average.

Which of the following is FALSE?
a. If you double each entry on a list, that doubles the mean.
b. If you double each entry on a list, that doubles the SD.
c. If you add 5 to each entry on a list, that adds 7 to the SD.
d. If you change the sign of each entry on a list, that changes the sign of the mean.
Answer:
c
Step-by-step explanation:
a. If you double each entry on a list, that doubles the mean. TRUE
b. If you double each entry on a list, that doubles the SD. TRUE
c. If you add 5 to each entry on a list, that adds 7 to the SD. FALSE
d. If you change the sign of each entry on a list, that changes the sign of the mean. TRUE
Therefore the only False statement is option c.

URGENT!!! Find the value of x using the similar trapezoids below.
Answer:
x= 30
Step-by-step explanation:
find the corresponding ratio AD:EH
20:12=5:3
is it constant? yes because 15:9 is also 5:3
if we're trying to find x on the larger side, we do x:18
what divides into 18 to equal 3? 6
we take 6 times 5 =30 so the ratio is now 30:18=5:3 so we know its correct

Answer:
The first one
Scale factor is 7
x = 3
The second one
Scale factor is 9
x = 99
Step-by-step explanation:
The first one
You can find out by dividing 49 by 7 which is 7
to find x = 21 divided by 7 is 3
The second one
You can find out by dividing 162 by 18 which is 9
to find x = 11 multiplied by 9 (since it is "opposite") is 99

A cheesecake recipe says, “Mix 12 oz of cream cheese with 15 oz of sugar."
a.
How many ounces of cream cheese are there for every ounce of sugar?
b.
How many ounces of sugar is that for every ounce of cream cheese?
Answer:
Step-by-step explanation:
(12 oz cream cheese)/(15 oz sugar) = (12/15 oz cream cheese)/(oz sugar)
= ⅘ oz cream cheese per ounce of sugar.
:::::
(15 oz sugar)/(12 oz cream cheese) = (15/12 oz sugar)/(oz cream cheese)
= 5/4 oz sugar per ounce of cream cheese.

Now find the measure of ∠YOZ. Which angle relationship did you use?
The angular measure of ∠YOZ is : 60° and the angular relationship used is vertically opposite angles(VOA).
How are angles formed?Angles are formed when two lines meet. this could be a direct intersection or an intersection between two parallel lines and a transversal.
Angles can be acute, obtuse, or reflex.
Analysis:
Given data:
∠VOX = 90°
∠WOX = 30°
∠WOX + ∠VOW = ∠VOX
30° + ∠VOW = 90°( the two angles are complementary that is they sum up to 90°)
∠VOW = 90 - 30 = 60°
∠VOW = ∠YOZ ( vertically opposite angles are equal)
∠YOZ = 60°.
in conclusion, the angular measure of ∠YOZ = 60° and the angular relationship used is vertically opposite angles.
