I did some digging and everywhere I look says there are 2 answers for x
#1.19
#2.-13

Personally I think it is A
Making width 19 and length 13

The answer is ou need to rewrite the equation to make it easy... and let it equal zero <span>2<span>x2</span>−8x+4=0</span> which will become <span>2(<span>x2</span>−4x+2)=0</span> you need to solve <span><span>x2</span>−4x+2=0</span><span> by completing the square or the general quadratic formula.</span>

A company produces packets of soap powder labeled "Giant Size 32 Ounces." The actual weight of soap powder in such a box has a N

Nataliya [291]

Answer:

C. 34.15 oz

Step-by-step explanation:

Problems of normally distributed samples are 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:

$\mu= 33, \sigma = 0.7$

How heavy does a box have to be for it to be labeled overweight?

Top 5%, so X when Z has a pvalue of 1-0.05 = 0.95.

So X when Z = 1.645.

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

$1.645 = \frac{X - 33}{0.7}$

$X - 33 = 0.7*1.645$

$X = 34.15$

So the correct answer is:

C. 34.15 oz

5$ is the cost and the cost per ride is 50 cent , if your parents give you 20$ . Write and solve a linear equation to find how m

Lesechka [4]

ANSWER= 30 rides

STEP-BY-STEP EXPLANATION

y=mx+b

m= $0.5 (per ride)

b= $5 (the cost)

x(rides) and y(parents money)

y= 0.5 x + 5

20= 0.5 x +5

20 - 5 = 0.5 x

15=0.5x

x= $\frac{15}{0.5}$

x=30 rides
