rise is 10
run is 8
10/8 is 5/4

Answer:

The unit rate is \frac{5}{4}


Step-by-step explanation:

we know that

The unit rate of the proportional relationship shown in the graph is equal to the slope of the line

The formula to calculate the slope between two points is equal to


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


we have


A(0,0)\ B(8,10)


Substitute the values


m=\frac{10-0}{8-0}


m=\frac{10}{8}


m=\frac{5}{4}

The equation of the linear direct variation is

y=\frac{5}{4}x

Help me please, I really need it​
Pachacha [2.7K]

Answer:

A OR C

Step-by-step explanation: I think it is A because in the question it says y=3

then y=ax²+b and on the A) it says a= -2 and b=2 OR the answer might be C) because it says ax² and a=<u>2 </u>

<u></u>

<u>im sorry if both of these are wrong and im sorry if you don't understand what i mean but i hope i helped you . :)</u>

A catering company provides packages for weddings and for showers. The cost per person for small groups
Tomtit [17]

Using the <em>normal distribution and the central limit theorem</em>, it is found that the probability the mean cost of the weddings is more than the mean cost of the showers is of 0.9665.

<h3>Normal Probability Distribution</h3>

In a normal distribution with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

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

  • It 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, which is the percentile of X.
  • By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation s = \frac{\sigma}{\sqrt{n}}.
  • When two variables are subtracted, the mean is the subtraction of the means, while the standard error is the square root of the sum of the variances.

<h3>What is the mean and the standard error of the distribution of differences?</h3>

For each sample, they are given by:

\mu_W = 82.3, s_W = \frac{18.2}{\sqrt{9}} = 6.0667

\mu_S = 65, s_S = \frac{17.73}{\sqrt{6}} = 7.2382

For the distribution of differences, we have that:

\mu = \mu_W - \mu_S = 82.3 - 65 = 17.3

s = \sqrt{s_W^2 + s_S^2} = \sqrt{6.0667^2 + 7.2382^2} = 9.4444

The probability the mean cost of the weddings is more than the mean cost of the showers is P(X > 0), that is, <u>one subtracted by the p-value of Z when X = 0</u>, hence:

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

By the Central Limit Theorem

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

Z = \frac{0 - 17.3}{9.4444}

Z = -1.83

Z = -1.83 has a p-value of 0.0335.

1 - 0.0335 = 0.9665.

The area of the parallelogram is 936 sq ft what’s the height
Makovka662 [10]

Answer:

h = 24 ft

Step-by-step explanation:

A = 936 ft^2, b = 39 ft.

A = bh

Divide both sides by b:

h = A/b = 936 ft / 39 ft = 24 ft
