Answer:

x = 18

Step-by-step explanation:

Given $3 \sqrt[4]{(x-2)^3}-4 = 20$

now adding '4' on both sides, we get

$3 \sqrt[4]{(x-2)^3}-4+4= 20+4$

$3 \sqrt[4]{(x-2)^3} = 24$

i) $3 \sqrt[4]{(x-2)^3}$ = 24

cancelling '3' on both sides, we get

$\sqrt[4]{(x-2)^3} = 8$

ii) $\sqrt[4]{(x-2)^3}$ = 8

iii) $(x-2)^{\frac{3}{4} } = 8$

$(x-2)^{\frac{3}{4} } = 2^{3}$

iv) $(x-2)^\frac{3}{4} )^{\frac{1}{3} } = (2^{3})^\frac{1}{3}$

now simplify on both sides,we get

$(x-2)^\frac{1}{4} = 2$

$((x-2)^{\frac{1}{4} })^4 = 2^4$

simplify we get solution is

v) (x-2) = 16

vi) final answer is x = 16 +2 =18

The number of chocolate chips in a popular brand of cookie is normally distributed with a mean of 22 chocolate chips per cookie

MA_775_DIABLO [31]

Answer:

The cutoff numbers for the number of chocolate chips in acceptable cookies are 16.242 and 27.758

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:

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

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:

$\mu = 22, \sigma = 3.5$
