Jude has to simplify the parenthesis first then multiply. She didn't follow PEMDAS
Answer:
icecream = $2.99
donut = $1.19
creamcake = $4.99
Step-by-step explanation:
The picture shows $7.17 for 2 x ice-cream and 1 donut
We are given 3 cream cakes that total 14.97 we divide by 3 = 4.99
9.17- 4.99=4.18
=5.37-4.18 =1.19
we can then fill out the boxes.
1.19 +1.19 = 2.38 = 5.37-2.38= £2.99
2.99 +2.99 +1.19 = $7.17
We can see total first two rows = $12.56
2.99+2.99+2.99 +1.19 +1.19+1.19 = $12.56
Answer:
We fail to reject H0; Hence, we conclude that there is no significant evidence that the mean amount of water per gallon is different from 1.0 gallon
Pvalue = - 2
(0.98626 ; 1.00174)
Since, 1.0 exist within the confidence interval, then we can conclude that mean amount of water per gallon is 1.0 gallon.
Step-by-step explanation:
H0 : μ= 1
H1 : μ < 1
The test statistic :
(xbar - μ) / (s / sqrt(n))
(0.994 - 1) / (0.03/sqrt(100))
-0.006 / 0.003
= - 2
The Pvalue :
Pvalue form Test statistic :
P(Z < - 2) = 0.02275
At α = 0.01
Pvalue > 0.01 ; Hence, we fail to reject H0.
The confidence interval :
Xbar ± Margin of error
Margin of Error = Zcritical * s/sqrt(n)
Zcritical at 99% confidence level = 2.58
Margin of Error = 2.58 * 0.03/sqrt(100) = 0.00774
Confidence interval :
0.994 ± 0.00774
Lower boundary = (0.994 - 0.00774) = 0.98626
Upper boundary = (0.994 + 0.00774) = 1.00174
(0.98626 ; 1.00174)
A=-112 bcs -216 ft is down from sea level and -104 is also down from sea level bcs both values are in minus but -104 is higher than other so you can minus it from -216 the difference is the answer
b=-109
