Answer: 27.4 hours
Step-by-step explanation:
According to the given statement "A survey of 45 teens found that they spent an average of 25.6 hours per week in front of a screen (television, computer, tablet, phone, etc.)."
Since the word average is synonym of word mean.
Therefore, the sample mean must have the nearest value to the given average.
From the given options 27.4 is the nearest value to the average of 258.6.
Hence, the population mean = 27.4 hours.
Answer:
option B. G
Step-by-step explanation:
Let
y ---->ounces of orange juice
x ---> ounces of pineapple juice
we know that
The ratio of orange juice to pineapple juice is equal to

substitute the given values

simplify

<u><em>Verify each graph</em></u>
Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
we have

that means
5 ounces of orange juice per 3 ounces of pineapple juice
Graph F
The slope is

Graph G
The slope is

Graph H
The slope is

Graph J
The slope is

The value of 2 is the value closest to 1.67
therefore
The graph that has a slope that best represents the ratio of orange juice to pineapple juice is Graph G
You would measure the length of a segment with a straightedge because it is free from curves and can help measure a segment because it is straight.
Nice
4s=amount of grams of protine in straberry for s ounces
3b=amount of grams of protine in banana for b ouces
total ounces is 6
s+b=6
total grams is 22
4s+3b=22
s+b=6
4s+3b=22
those are the 2 equations
a.
s+b=6
4s+3b=22
b. elmination, we can elminate alll the b's and have 1s left
c.
multiply first equaiton by -3 and add to second
4s+3b=22
<u>-3s-3b=-18 +</u>
1s+0b=4
s=4
sub
s+b=6
4+b=6
minus 4
b=2
4 oz straberry
2 oz banana
