What is the answer to this ?
harina [27]

Answer:

The answer is option 1.

Step-by-step explanation:

In order to solve x, you have to make x the subject, by multiplying each sides by 5, to get rid of 5 on the left side.

\frac{x}{5}  = 8

\frac{x}{5}  \times 5 = 8 \times 5

x = 40

A company manufactures 2,000 units of its flagship product in a day. The quality control department takes a random sample of 40
shepuryov [24]

Answer:

B

Step-by-step explanation:

The recommended sample size n for point estimates is:

n = NX / (N + X - 1)

where N is the population size, and X is defined as:

X = Z² p (1 - p) / E²

where Z is the critical value, p is the sample proportion, and E is the margin of error.

Assume a confidence level of level of 95% and a margin of error of 5%.

α = 0.05, Z(α/2) = 1.96

E = 0.05

Of the 40 units tested, 2 had lifespans less than 26 days.  So the proportion is:

p = 2/40 = 0.05

Therefore:

X = (1.96)² (0.05) (1 - 0.05) / (0.05)²

X = 73

Given N = 2000:

n = (2000) (73) / (2000 + 73 - 1)

n = 70.45

Rounding, the recommended sample size is 70.

Steven converted $1,000 to ×105,000 for a trip to Japan. However, he spent only ×50,000. During this period, the value of the do
Mariulka [41]

Answer:

E

Step-by-step explanation:

We were told Steven spent an amount of 50,000. Although the value of the dollar against the yen has changed. So therefore, to calculate the amount of money he spent, we would be needing to divide the amount he spent over the present exchange rate of the dollars to yen.

We then divide the 50,000 by 100 and that equals $500.

Hence, the amount of money spent by Steven is simply $500

In French club <span>there are
10 freshman
</span><span>12 sophomores
15 juniors
30 seniors

total of the members------> (10+12+15+30)=67
total </span> freshman-----> 10

so
<span>the probability that a freshman will be chosen=10/67
and 
</span><span>the probability that a freshman will not be chosen=(67-10)/67
</span>the probability that a freshman will not be chosen=57/67---> 0.8507
0.8507= 85.07%

the answer is
the probability that a freshman will not be chosen is 85.07%
