Answer:

<h2>D = 75°</h2><h2>E = 37°</h2><h2>F = 68 ° Given </h2>

Step-by-step explanation:

$(13x - 3) + (6x + 1) + (68) = 180 \\ 19x + 66 = 180 \\ 19x = 180 - 66 \\ x = \frac{114}{19} \\ x = 6 \\ \\ \\ d = 13x - 3 \\ d = 13(6) - 3 \\ d = 75 \\ \\ e = 6x + 1 \\ e = 6(6) + 1 \\ e = 37 \\ \\ f = 68 \\ \\ check \: \: \: 75 + 37 + 68 = 180$

I hope that is useful for you :)

5 DIVIDED BY 1/4 hURRY PLEASE

Anni [7]

Hello!

1/4 is equal to 0.25. Let's divide below.

5/0.25=20

When dividing by fractions, you multiply by the reciprocal. The reciprocal of 1/4 is 4, and 5(4)=20

Therefore, our answer is 20.

I hope this helps!

Answer:

a. 5.26

t score=Xbar A- Xbar B/Sd of difference of means

t score=55-51/0.76

t score=4/0.76=5.26
