Answer:
g - 12
Step-by-step explanation:
First, you divide the 16/4 which will get you 4, then subtract it by 16 which will get you -12, so now it is g - 12
Answer:
$13
Step-by-step explanation:
$26,555 ÷ 36 = 737.6388889 ≈ $738 per month
36 × 738 = $26,568
= $13
Factor the 25 where they multiply to make 25 and add to make 10 so now it's (x+5)and (x+5) so x=-5 because x+5=0 solved
Answer:
(a) The 26th percentile for the number of chocolate chips in a bag is 1185
(b) The number of chocolate chips in a bag that makes up the middle 96% of the bags is between 1020 and 1504
Step-by-step explanation:
From the question, we have the following values:
μ =1262 and σ =118
(a) Let the value of x represents the 26th percentile. So the 26th percentile means 26% data is less than x. We can use the standard normal table to get the particular z-value that corresponds to this percentile.
P( Z<-0.65 )=0.2578 which is approximately 0.26
So for 26th percentile z-score will be -0.65.
Mathematically;
z-score = (x-mean)/SD
-0.65 = (x-1262)/118
-76.7 = x -1262
x = 1262-76.7 = 1185.3
This value is approximately 1,185
(b) Using a graph of standard normal distribution curve, if middle is 96% , then at both tails 2% each.
From z-table, we can find the closest probability;
P(-2.05<z<2.05) = 0.96
So we have two x values to get from the individual z-scores
-2.05 = (x-1262)/118
x = 1020(approximately)
For 2.05, we have
2.05 = (x-1262)/118
x = 1262 + 2.05(118) = 1504 (approximately)
Width= x
Length: 80+x
p=2(l+w)
320=2(80+x+x)
320=2(80+2x)
320=160+4x
320-160=4x
160=4x
160/4=x
40yd=x
The width is 40 yds and the length is 80+40=120 yards
Hope I helped :)
