Answer:
do you have a picture of this
Answer:
width = 25 ft
Step-by-step explanation:
SA = 2lh + 2lw + 2wh
5278 = (2)(23)(43) + (2)(23)(w) + (2)(w)(43)
reduce:
5278 = 1978 + 46w + 86w
subtract 1978 from each side:
3300 = 132w
divide both sides by 132
w = 25

Answer:
y = -7x
Step-by-step explanation:
The line goes through the origin, so the y-intercept is b=0.
The line goes through the point (1, -7), so has a "rise" of -7 for a "run" of 1. The slope is ...
m = rise/run = -7/1 = -7
Then the slope-intercept form equation is ...
y = mx + b
y = -7x

When fourteen different second-year medical students measured the blood pressure of the same person, they obtained the result listed below. Assuming that the population standard deviation is known to be 9, construct and interpret a 99% confidence interval estimate of the population mean.
Data: 128 121 129 128 123 137 138 147 122 144 125 140 134 125
Answer:
The 99% confidence interval estimate of the population mean is between 125.3 and 137.7. This means that we are 99% sure that the true population mean, that is, the mean blood pressure of all second-year medical students, is in this interval.
Step-by-step explanation:
The first step is finding the sample mean, which is the sum of all 14 blood pressures, divided by 14. So
[tex]S = \frac{128 + 121 + 129 + 128 + 123 + 137 + 138 + 147 + 122 + 144 + 125 + 140 + 134 + 125}{14}[/tex]
[tex]S = 131.5[/tex]
Confidence interval:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 2.575\frac{9}{\sqrt{14}} = 6.2[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 131.5 - 6.2 = 125.3
The upper end of the interval is the sample mean added to M. So it is 131.5 + 6.2 = 137.7
The 99% confidence interval estimate of the population mean is between 125.3 and 137.7. This means that we are 99% sure that the true population mean, that is, the mean blood pressure of all second-year medical students, is in this interval.

Mike and his sister did some laundry at the laundromat. To wash a load costs $2 and to dry a load costs another $2. Mike and his sister washed and dried 4 loads of laundry. They also had to buy 4 packets of detergent for $1 per packet. How much money did Mike and his sister spend to do their laundry?
a) $16
b) $28
c) $12
d) $20
Answer:
answer is d) $20
Step-by-step explanation:
because 2x4=8 + 2x4=8 = $16 then 4 packets for $1 is $4 16+4= $20
Answer:
D) $20
Step-by-step explanation:
Wash plus dry = $4
$4 times 4 times = $16
$1 for one detergent times the four packets = $4
Total is $20

Answer:
x=1
y=-2
Step-by-step explanation:
2x-3y=8
4x+3y=-2
When we add the two equations, the y’s cancel out and we’re left with
6x=6
x=1
Now that we know x=1, we put it back in one of the equations to find y.
2(1)-3y=8
-3y=6
y=-2
Solve the proportion.
20/13 = 60/d
d=
Answer:
[tex]d = 39[/tex]
Step-by-step explanation:
1) Multiply both sides by d.
[tex] \frac{20}{13} d = 60[/tex]
2) Simplify 20/13d to 20d/13.
[tex] \frac{20d}{13} = 60[/tex]
3) Multiply both sides by 13.
[tex]20d = 60 \times 13[/tex]
4) Simplify 60 × 13 to 780.
[tex]20d = 780[/tex]
5) Divide both sides by 20.
[tex]d = \frac{780}{20} [/tex]
6) Simplify 780/20 to 39.
[tex]d = 39[/tex]
Therefor, the answer is d = 39.

Is 7/12 greater than or less than 4/3
Answer:
[tex]\frac{7}{12}[/tex] is less than [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
Hi there,
When solving this problem, it is highly recommended to have the same denominator. This will make it significantly easier to answer these types of questions.
Since three is a factor of 12, we can multiply the denominator by four to get the same denominator value. This makes [tex]\frac{4}{3}[/tex] equivalent to [tex]\frac{16}{12}[/tex].
Now that we have the same denominator, it is clear that [tex]\frac{7}{12}[/tex] is less than [tex]\frac{4}{3}[/tex].
Hope this gives you a clearer idea about this concept. Cheers.

Buy any mistakes in the renaming of the fractions below show the correct remaining 9 / 4 = 9 / 12 2 / 3 + 6 / 12
Step-by-step explanation:
3/4=9/12 CORRECT
2/3=6/12 FALSE
Step-by-step explanation:
What is done to top of the fraction must be done to the bottom as well in order for the renaming to be true.
3*3 = 9
4*3 = 12
Therefore proven to be true
However,
2*3 = 6
but 3*3 = 9
The second fractions is renamed incorrectly and should be either 2/4=6/12 or 2/3=2/9
Hope this helps!
