Answer:

11 weeks

Step-by-step explanation:

If we multiply 50 by 11 we get 550 with a remainder of 100, if we're to take out another 50 for another week we would have 50 dollars remanding but the question says that we need to have at least 75 remaining so this will not be possible. Therefor 11 weeks is our answer.

I hope this helps have a great day :)

Answer:

Let S = starting point

Let ST = length of tunnel

SR = 1414 m

RT = 2236 m

Set up:

ST^2 + SR^2 = RT^2

ST^2 + (1414)^2 = (2236)

Solve for RT to find your answer.

Warren, a golf fan, was curious about how often professional golfers make successful putts from various distances. He looked at

Answer:

Explained below.

Step-by-step explanation:

A correlation coefficient is a mathematical measure of certain kind of correlation, in sense a statistical relationship amid two variables

Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.

Values amid 0.7 and 1.0 (-0.7 and -1.0) implies a strong positive (negative) linear relationship amid the variables.

It is provided that Warren noticed a strong negative linear relationship between the success rate and putt distances.

This implies that as the putt distances are increasing the success rates are decreasing and as the putt distances are decreasing the success rates are increasing.

Answer:

X=35

Step-by-step explanation:

Those 2 angles equal each other, meaning they're the same.

Knowing that you put them to equal each other.

2x+15=3x-20

Then you solve it.

20+15=3x-2x

35=1x

X=35

Write 7/10 as a sum of fractions three diffrent ways

Elanso [62]

Answer:

3/10 + 4/10

1/2 + 1/5

1/10 + 3/5

Step-by-step explanation:

3/10 + 4/10 = 7/10 (add numerator and keep denominator)

1/2 + 1/5 = 5/10 + 2/10 = 7/10 (use equivalent fractions)

1/10 + 3/5 = 1/10 + 6/10 = 7/10

I hope this helped and please mark me as brainliest!

A researcher is using a two-tailed hypothesis test with α = .05 to evaluate the effect of a treatment. If the boundaries for the

Solnce55 [7]

Answer:

A. n = 22

Step-by-step explanation:

Hello!

The researcher conducted a one-sample t-tas with the following hypotheses:

H₀: μ = μ₀

H₁: μ ≠ μ₀

α:0.05

The one-sample t-test has "n-1" degrees of freedom and since the hypotheses are two-tailed you know that the rejection region will be divided into two tails with "α/2" for each tail. ± $t_{n-1;1-\alpha /2}$

If α:0.05 then α/2:0.025 and 1-α/2= 0.975

Using the given sample sizes as a reference you look in the table for the corresponding DF for an accumulated probability of 0.975

For n = 22 $t_{21;0.975}= 2.080$

For n= 21 $t_{20;0.975}= 2.086$

For n= 20 $t_{19;0.975}= 2.093$

The correct answer is a) n= 22

I hope this helps!
