Two workers can make two chairs in two days. How many chairs can 8 workers working at the same rate make in 20 days?

Vlad [161]

So we know that 2 workers can make 2 chairs in 2 days. Therefore if we use that same proportion, we will find that 8 workers can make 8 chairs in 2 days.

But the question is asking for 20 days, so we must multiply this by 10.

So, when we multiply 8 by 10, we find that in 20 days, 8 workers can make 80 chairs.

When Ryan counted some dimes and quarters he had 196 coins and a total of $39.40. How many coins of each kind does Ryan have?

Nonamiya [84]

Quarters = x
dimes = 196 - x

10(196 - x) + 25x = 3940
1960 - 10x +25x = 3940
1960 + 15x = 3940
15x = 1980
x = 132

169 - 132 = 64

Therefor there are 132 quarters and 64 dimes

The two intervals (114.9, 115.7) and (114.6, 116.0) are confidence intervals (computed using the same sample data) for μ = true

kenny6666 [7]

Answer:

115.3 hertz

Step-by-step explanation:

For either interval, the value of the sample mean is given by the average of the lower and upper bound of the confidence interval. Since both intervals were constructed by using the same sample, both values should be equal.

For the first interval:

$M=\frac{114.9 + 115.7}{2} \\M=115.3\ hertz$

For the second interval:

$M=\frac{114.6 + 116.0}{2} \\M=115.3\ hertz$
