Answer:
The sample mean year is 1261 A.D.
The standard standard deviation is of 46 A.D.
Step-by-step explanation:
Sample mean:
Sum of all values divided by the number of values. So
[tex]x = \frac{1271+1187+1194+1250+1268+1316+1275+1317+1275}{9} = 1261.4[/tex]
Rounding to the nearest whole number, the sample mean year is 1261 A.D.
Sample standard deviation:
Square root of the sum of the difference squared between each value and the mean, divided by one less than the sample size. So
[tex]s = \sqrt{\frac{(1271-1261.4)^2+(1187-1261.4)^2+(1194-1261.4)^2+(1250-1261.4)^2+(1268-1261.4)^2+(1316-1261.4)^2+(1275-1261.4)^2+(1317-1261.4)^2+(1275-1261.4)^2}{8}} = 45.8[/tex]
Rounding to the nearest whole number, the standard standard deviation year is of 46 A.D.

Step-by-step explanation:
We need to multiply 5 by 4y and 5 by 2 y
20y + 10y = 30y
Answer:
30 y
Step-by-step explanation:
You are supposed to distribute(multiply) the 5 with 4y+2y inside the parentheses. Just multiply the 4y by 5 to get 20y and then 2 y with 5 to get 10 y. Your answer should be come out to be 20y + 10y. Since they both use the same variable (y), add them together to get 30y
The total simple interest owed on a loan of $8,000 after 60 months is $1,280.
What is the yearly interest rate on the loan? Show your work.
Simple interest is an interest added on an amount of money. The yearly interest rate is 1.05%
Simple interestSimple interest is an interest added on an amount of money. The formula for calculating amount is given as:
Amount. = Principal + Interest
8000 = 1280 + PRT
Substitute
8000 - 1280 = 1280(R)(5)
6720 = 6400R
R = 1.05
Hence the yearly interest rate is 1.05%

Answer:
a. A researcher wants to compare the hand–eye coordination of men and women. She finds a random sample of 100 men and 100 women, and measures their hand–eye coordination = paired samples
b. A researcher wants to know whether professors with tenure have fewer office hours than professors without tenure. She observes the number of office hours for professors with and without tenure. = independent samples

Which of the following is a solution to the equation: y = 7x + -59? Choose all that apply.
Select all that apply:
O (8,-3)
O (9,8)
O (7,-3)
0 (10,5)
Answer:
[tex](a)\ (8,-3)[/tex]
Step-by-step explanation:
Given
[tex]y =7x +-59[/tex]
Required
Select all solutions
[tex](a)\ (8,-3)[/tex]
This implies that:
[tex]x = 8; y=-3[/tex]
So:
[tex]y =7x +-59[/tex]
[tex]-3 =7 * 8 + -59[/tex]
[tex]-3 =7 * 8 -59[/tex]
[tex]-3 =56 -59[/tex]
[tex]-3 =-3[/tex]
The above is a solution:
[tex](b)\ (9,8)[/tex]
This implies that:
[tex]x=9\ y =8[/tex]
So:
[tex]y =7x +-59[/tex]
[tex]8 =7 * 9 + -59[/tex]
[tex]8 =7 * 9 -59[/tex]
[tex]8 =63 -59[/tex]
[tex]8 =4[/tex]
The above is not a solution because [tex]8 \ne 4[/tex]
[tex](c)\ (7,-3)[/tex]
This implies that:
[tex]x=7;\ y=-3[/tex]
So:
[tex]y =7x +-59[/tex]
[tex]-3 = 7 * 7 +-59[/tex]
[tex]-3 = 7 * 7 -59[/tex]
[tex]-3 = 49 -59[/tex]
[tex]-3 = -10[/tex]
The above is not a solution because [tex]-3\ne -10[/tex]
[tex](d)\ (10,5)[/tex]
This implies that:
[tex]x =10; y=5[/tex]
So:
[tex]y =7x +-59[/tex]
[tex]5 = 7 * 10 + -59[/tex]
[tex]5 = 7 * 10 -59[/tex]
[tex]5 = 70 -59[/tex]
[tex]5 = 11[/tex]
The above is not a solution because [tex]5 \ne 11[/tex]

A cook places two thirds of a pound of garlic powder in a plastic container. This occupies one third of the space in the container. How much pounds of a powder can be stored in this container?
Answer:
1
Step-by-step explanation:
Add e
Number of pounds of a powder that can be stored in the container is 2 pounds.
What are Fractions?Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.
Here, a is called the numerator and b is called the denominator.
Given that,
Number of pounds of garlic powder placed in container = 2/3 pound
This is equal to one third of the total space in the container.
So, we can write this as,
Number of pounds of powder in 1/3 space = 2/3 pounds
Number of pounds of powder in 1 full space = 2/3 ÷ 1/3
= 2/3 × 3 (by reciprocal rule)
= 2 pounds
Hence 2 pounds can be stored in the full container.

You are playing blackjack and want to know the probability of getting dealt certain cards. In blackjack two cards are drawn from a deck, the first is dealt to you face down and the second is dealt face up. Using the product rule, find the probability that (a) The bottom card is an ace or a king and the top card is red. (b) Both of the cards are clubs. (c) At least one of the cards is a jack.
Answer:
The correct answer is:
(a) 0.0784
(b) 0.0588
(c) 0.1493
Step-by-step explanation:
According to the question,
Number or ace or king,
n (ace or king) = 8
Number of red,
n (red) = 26
Number of club,
n (club) = 13
Number or jack,
n (jack) = 4
(a)
Probability of 1st ace or king and 2nd in red will be:
⇒ [tex]P(ist \ ace \ or \ king \ and \ 2nd \ red) = \frac{8}{52}\times\frac{26}{51}[/tex]
⇒ [tex]=0.0784[/tex]
(b)
Probability of both clubs will be:
⇒ [tex]P(clubs) =\frac{13C_2}{52C_2}[/tex]
⇒ [tex]=0.0588[/tex]
(c)
Probability of at least one is jack will be:
⇒ [tex]P(at \ least \ one \ is \ jack)=1-P(none \ jack)[/tex]
⇒ [tex]=1-\frac{48C_2}{52C_2}[/tex]
⇒ [tex]=0.1493[/tex]

numerator: 1*4 = 4
denominator = 2 * 5 = 10
Answer: 4 / 10 but this will reduce. Divide Top and Bottom by 2
4/2 = 2
10/2 = 5
Answer: 2/5
The way you should answer is 2 because the question gives you the fact that it is in 5ths. If you get it wrong then put in 2/5.
