A is correct because f(1)=3^1+1 so f(1)=4 and g(x)=4 so f(x)=g(x)

B is also correct because the ordered pair we get is (1,4) and this is in quadrant 1

C is incorrect

D is incorrect

E is incorrect

Ans: A and B are correct

Ratios- coca cola has 65g sugars total. Equivalent amount of carrots: 1.383 kg or approx 3 lbs. so question asks

dimaraw [331]

This question means that Coca-Cola, which has 65 grams of sugar in a can (I assume), has the same sugar content as 1.383 kg of carrots. Coca-Cola is a distractor in this problem. (1.383kg/65g)=(1kg/s) Can you solve from there for s?

The time that it takes a randomly selected job applicant to perform a certain task has a distribution that can be approximated b

Answer:

A task time of 177.125s qualify individuals for such training.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by

$Z = \frac{X - \mu}{\sigma}$

After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X. Subtracting 1 by the pvalue, we This p-value is the probability that the value of the measure is greater than X.

In this problem, we have that:

A distribution that can be approximated by a normal distribution with a mean value of 145 sec and a standard deviation of 25 sec, so $\mu = 145, \sigma = 25$ .
