Step-by-step explanation:
The formula on getting the area of a rectangle is width x height. Therefore you just have to multiply 8 (height) to 7 (width). the answer is ^^^
Answer:
use formula length × width ×height

plug in what they have given you
Answer:
5
Step-by-step explanation:
We know that Karen divided her garden into equal parts of which she intend to plant corn in ⁸/20 of it.
This implies that she divide the garden was divided into 20 parts.
To determine the fewer number of parts she can divide her garden into, simply ⁸/20.
Thus:
8/20 = (2*4)/(5*4)
= ²/5 (4 cancels out 4)
Therefore, this implies that the least number of parts she can divide her garden into is 5.
Answer:
5.5-1.5= 4.
4*0.95= 3.8
so the mid weight is 3.8oz.
Answer:
(0.5455 ; 0.7545)
Step-by-step explanation:
Given that:
Sample size, n = 80
Baseball fans, x = 52
Proportion, p = x/n = 52 / 80 = 0.65
Using the relation :
Confidence interval :
p ± Zcrit√[(p(1 -p))/n]
Zcrit at 95% = 1.96
Lower boundary: p - Zcrit√[(p(1 -p))/n]
0.65 - 1.96√[(0.65(1 -0.65))/80]
0.65 - 1.96√[(0.65(0.35))/80]
0.65 - 1.96 * √0.00284375
0.65 - (1.96 * 0.0533268)
0.65 - 0.104520528
= 0.545479472
Upper boundary: p + Zcrit√[(p(1 -p))/n]
0.65 + 1.96√[(0.65(1 -0.65))/80]
0.65 + 1.96√[(0.65(0.35))/80]
0.65 + 1.96 * √0.00284375
0.65 + (1.96 * 0.0533268)
0.65 + 0.104520528
= 0.754520528
(0.5455 ; 0.7545)
