Plss help wats the slope

Mathematics
1 answer:
mars1129 [50]3 years ago
4 0

Answer:

\frac{3}{2}

Step-by-step explanation:

To find the slope, we use the formula:

M = \frac{y2 - y1}{x2-x1}

So, plug in our numbers. For reference:

-2 = x1       2 = y1

0 = x2       5 = y2

2 = x3       8 = y3

After plugging in:

M = \frac{5 - 2}{0 - - 2} = \frac{3}{2}

Thus, your slope is \frac{3}{2}.

IQ scores are known to be normally distributed. The mean IQ score is 100 and the standard deviation is 15. What percent of the p
Masja [62]

Answer:

47.06% of the population has an IQ between 85 and 105.

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 = 100, \sigma = 15

What percent of the population has an IQ between 85 and 105?

This is the pvalue of Z when X = 105 subtracted by the pvalue of Z when X = 85. So

X = 105

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

Z = \frac{105 - 100}{15}

Z = 0.33

Z = 0.33 has a pvalue of 0.6293.

X = 85

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

Z = \frac{85 - 100}{15}

Z = -1

Z = -1 has a pvalue of 0.1587

So 0.6293 - 0.1587 = 0.4706 = 47.06% of the population has an IQ between 85 and 105.

How do I solve this question? Rayne sold 3 desks at a local trade show. he payed $4.00 to rent the booth. he gave half of his re
ra1l [238]

Answer:

$125

Step-by-step explanation:

I suspect there's an error in the problem statement.  Revenue is the money made from selling the desks.  Profit is the revenue from the desks minus the cost of the booth rental.

If Rayne gives half of his <em>profit</em> to the carpenter, and x is the price per desk, then:

185.50 = ½ (3x − 4)

371 = 3x − 4

375 = 3x

x = 125
