Answer:

<h2>d = 3</h2>

Step-by-step explanation:

\dfrac{5}{2}=d-\dfrac{2}{4}\qquad\left/\dfrac{2}{4}=\dfrac{2:2}{4:2}=\dfrac{1}{2}\right/\\\\\dfrac{5}{2}=d-\dfrac{1}{2}\qquad\text{add}\ \dfrac{1}{2}\ \text{to both sides}\\\\\dfrac{5}{2}+\dfrac{1}{2}=d-\dfrac{1}{2}+\dfrac{1}{2}\\\\\dfrac{5+1}{2}=d\\\\\dfrac{6}{2}=d\to d=3

Answer:

200

Step-by-step explanation:

1. 4 times 5 because there are 5 types in total and they make 4 of each type in each batch they bake. 4*5 is 20.

2. 20 times 10 because they make 10 batches and you know there are 20 in each batch. so 20 times 10 is 200.

200 is the answer.

What is the absolute davatation round to the nearest tenth for 6.3, 6.4, 6.5, 6.6, 6.8. 6.8, 7.5?
WITCHER [35]
Let's find the mean of all the values first.
6.3+6.4+6.5+6.6+6.8+6.8+7.5= 46.9
Let's divide by the number of values.
46.9÷7=
6.7
Now let's find the distance that each number is away from 6.7 and find the mean of those numbers.
0.4+0.3+0.2+0.1+0.1+0.1+0.8=
.2857
≈ 0.3
So, the absolute deviation is 0.3.
