Answer:

b. $(1,6]$

Step-by-step explanation:

The given inequality is $1\:$ .

We use the parenthesis $()$ to represent an open interval < or >.

We use the square brackets $[]$ to represent a closed interval $\le$ or $\ge$ .

$1\:$ represents $(1,6]$ .

The correct choice is B.

Answer:

Step-by-step explanation:

You are given the double inequality

$1$

This means that x is greater than 1 and less than or equal to 6.

Thus, point 1 must be excluded (with bracket "(") and 6 must be included (with bracket "]").

Hence, the correct answer is $(1,6].$

Emmanuel brought 28 lb of potting soil this week. This amount is 4 lb more than twice the amount of potting soil he brought last

jek_recluse [69]

(a) how much potting soil he bought last week
(b) 28 = 2p + 4
(c) 28 = 2p + 4....subtract 4 from both sides
28 - 4 = 2p...simplify
24 = 2p...divide both sides by 2
24/2 = p....simplify
12 = p......12 solves the equation
(d) He bought 12 lbs of potting soil last week

Consider a value to be significantly low if its z score less than or equal to minus−2 or consider a value to be significantly hi

den301095 [7]

Answer:

Test scores of 10.2 or lower are significantly low.

Test scores of 31 or higher are significantly high

Step-by-step explanation:

Z-score:

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

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

The Z-score measures how many standard deviations the measure is from the mean. 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, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 20.6, \sigma = 5.2$
