Answer:

Step-by-step explanation:

You first have to simplify...

-2x-4=3x+1 (-1 both sides)

-2x-5=3x (+2x both sides)

-5=5x

-1=x

So graphing that would be a vertical line on -1.

How would I solve this equation? I also would like the steps please.

bagirrra123 [75]

Answer:

The answer to your question is x = 23.36

Step-by-step explanation:

$\frac{1250}{1.04^{x} } = 500$

Solve for x

1250 = 500(1.04) $^{x}$

$\frac{1250}{500} = 1.04^{x}$

Apply logarithms

$2.5 = 1.04^{x}$

log 2.5 = x log 1.04

x = 0.398 / 0.017

x = 23.36

The time to complete the construction of a soapbox derby car is normally distributed with a mean of three hours and a standard d

Bezzdna [24]

Answer:

0% probability that it would take exactly 3.7 hours to construct a soapbox derby car

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.

Also, the probability of finding an exact value in the normal probability distribution is 0.

0% probability that it would take exactly 3.7 hours to construct a soapbox derby car
