Answer: The fourth choice is correct

Step-by-step explanation: If Geraldo has fewer marbles, x has to represent the larger amount that Yan owns. So Yan's number plus Geraldo's smaller number equals the total.

Arisa [49]

Answer:

at least three are dimes

so we have 20 coins with a total of 3.50

if the rest are all quarters then there would be 4*3+2=14 but we need 20

so we are 6 short

we must have dimes in multiples of 5

12 q + 5 d=3.50 but only 17 coins

10q +10 dimes=3.50 with 20 coins

10 q +13 dimes total

algebraic solution

d+q=23

25q+10d=380

d=23-q

Consider a paint-drying situation in which drying time for a test specimen is normally distributed with s = 6. The hypotheses H0
adell [148]

Answer:

There is no statistical evidence to support the claim that the mean is elss than 74.

Step-by-step explanation:

Given that  a paint-drying situation in which drying time for a test specimen is normally distributed with s = 6.

The hypotheses H0: µ = 74 and Ha: µ < 74

are to be tested using a random sample of n = 25 observations

a) Z = \frac{72.3-74}{\frac{6}{\sqrt{25} } } \\=-1.417

ie. -1.417 std deviations to the left of mean.

b) p value = 0.078241

Since p > 0.01 , our alpha, accept H0

There is no statistical evidence to support the claim that the mean is elss than 74.
