Assume that a simple random sample has been selected and test the given claim.Claim: The average age of actresses when they win an acting award is more than 34 years oldTo test this claim a simple random sample (SRS) of 27 actresses is used. This sample of 27 actresses had a sample mean of 31.4 years and a standard deviation = 11.2 years. Assume the the distribution of actresses ages is approximately normal.Select all TRUE statements from those given below..For this hypothesis test; H0: ? 34 H1: ?>342. The correct decision is to "support" (fail to reject) the null hypothesis H0.3. We decide to reject the claim that the average age of actresses when they win an acting award is more than 34 years old.4. For this hypothesis test, the P-value = .8815. For this hypothesis test, the test statistic is t = -1.21

Answer:

Step-by-step explanation:

Least common multiple can be found by multiplying the highest exponent prime factors of 36 and 48. First we will calculate the prime factors of 36 and 48.

Prime Factorization of 36

Prime factors of 36 are 2, 3. Prime factorization of 36 in exponential form is:

36 = 22 × 32

Prime Factorization of 48

Prime factors of 48 are 2, 3. Prime factorization of 48 in exponential form is:

48 = 24 × 31

Now multiplying the highest exponent prime factors to calculate the LCM of 36 and 48.

LCM(36,48) = 24 × 32

LCM(36,48) = 144

List of positive integer factors of 36 that divides 36 without a remainder.

1, 2, 3, 4, 6, 9, 12, 18

Factors of 48

List of positive integer factors of 48 that divides 36 without a remainder.

1, 2, 3, 4, 6, 8, 12, 16, 24

Greatest Common Factor Number

We found the factors and prime factorization of 36 and 48. The biggest common factor number is the GCF number.

So the greatest common factor 36 and 48 is 12.

Answer:

the least is 144 the highest is 12

it's the set that will add to 180°

36° + 42° + 102° = 180°

Answer:

Step-by-step explanation:

This is because here,

36° + 42° + 102° = 180°

Hence, a triangle can be made.

Answer: The answer is 4 units to the left of 11

Step-by-step explanation: First you get the answer -4+11=7 so then on the number line you have to find which of those options gets you 7 which will be 4 units to the left of 11 since the left is going less then 11 in the end you will get 2 places more to the right of the 5 on the number line making the number 7 there.

Answer:

x = 8.66

Step-by-step explanation:

Apply pythagorean theorem to find the value of x.

Thus:

x² = 14² - 11²

x² = 75

x = √75

x = 8.66025404

x = 8.66 (nearest hundredth)

Answer:

1) if tₙ = 3*n - 2, we want to find the value of S(5), which is the sum of the first 5 terms.

We can simply compute the sum directly, it is:

S(5) = t₁ + t₂ + t₃ + t₄ + t₅

S(5) =  (3*1 - 2) +  (3*2 - 2) + (3*3 - 2) + (3*4 - 2) + (3*5 - 2)

S(5) = 35

Then the correct option here is a).

2) This is not correctly written.

I will assume that we the n-th term is:

tₙ = n^2 + 3*n

And we want  S(5) again

Then:

S(5) = t₁ + t₂ + t₃ + t₄ + t₅

S(5) = (1^2 + 3*1) + (2^2 + 3*2) + (3^2 + 3*3) + (4^2 + 3*4) + (5^2 + 3*5)

S(5) = 100

So the correct option is (d)

(Notice that if we had chosen any other S(n), the answer is still option (d) )

Macro can finish the puzzle in 3 hours. We can say that her speed for working is 1/3 or 1/3 puzzle per hour.

Now if they work together, this turns into 1 puzzle per hour.

That must mean that Cliff would be doing the other 2/3 of the puzzle while Macro does his 1/3 in that hour. If Cliff has a speed of doing them 2/3 per hour. Then it would take 1 and a half hour to finish 1 whole puzzle.

Answer:

Step-by-step explanation:

The average rate of change in the value of the account for the first 3 years

is $1.58.

When the independent variable is in the power of some function we call them an exponential function, For example, [tex]e^x[/tex] is an exponential function.

Given, The value of the account, in dollars, can be modeled as

[tex]V(t) = 30(1.05)^t[/tex].

Now at t = 3 or after 3 years, it is [tex]V(t) = 30(1.05)^3[/tex].

V(3) = $34.73 and he initially deposited $30.

So, The average rate of change is $(34.73 - 30)/3 = $(4.73)/3 = $1.58.

Answer:

Step-by-step explanation:

The distance between the points will be the difference between the points as shown;

Difference = -2.1 - (-2.6)

Difference = -2.1 + 2.6

Difference = 2.6 - 2.1

Difference = 0.5

Hence the difference between the numbers -2.6 and -2.1 on the number line is 0.5

Answer:

Equation - $1000=$300+$7.50x

Answer - Mr. Chamberlain can included 93 Student Entries

Step-by-step explanation:

$1000 (budget)

$300 (cost to rent bus)

$7.50 (cost of each student entry)

$1000-$300= $700

Now we have found out that Mr. Chamberlain has $700 left to spend on student entries.

$700/$7.50 = 93.333

Round 93.333 down to 93 because you can't have 1/3 of a student (obviously)

93 = the max number of student entries that Mr. Chamberlain can have for the museum field trip
