Answer:

Step-by-step explanation:

y = -4x + 7

perp. 1/4

y - 3 = 1/4(x + 8)

y - 3 = 1/4x + 2

y = 1/4x + 5

Use the formula . Find t for r = 33.2 m/h and d = 375.16 m.

Butoxors [25]

$\boxed{t=11.3h}$

<h2>Explanation:</h2><h2></h2>

In this problem we have the following data:

$r:speed \\ \\ d:distance \\ \\ t:time \\ \\ \\ r=33.2m/h \\ \\ d=375.16m \\ \\ \\ So \ our \ goal \ is \ to \ find \ t$

Speed, time and distance are related with the following formula:

$r=\frac{d}{t} \\ \\ \\ Solving \ for \ t: \\ \\ t=\frac{d}{r} \\ \\ t=\frac{375.16}{33.2} \\ \\ \boxed{t=11.3h}$

Select the equation that is in slope-intercept form A y+1=5x-2 B y=-2x+15 C 3x=-4y+9 D -5x+3y=6

inysia [295]

Slope intercept form looks like:

y = mx + b

-------------------------------------------------------------------------------------------------------------------

Choose the one that follows the formula

B) y=-2x+15 is your answer.

-2 = m

15 = b

As an introduction to probability, a student asked to roll a fair, six sided number cube seven times the results of those seven

frosja888 [35]

Using it's concept, the standard deviation of the data is of 3.742.

<h3>What are the mean and the standard deviation of a data-set?</h3>

The mean of a data-set is given by the <u>sum of all values in the data-set, divided by the number of values</u>.

The standard deviation of a data-set is given by the square root of the <u>sum of the differences squared between each observation and the mean, divided by the number of values</u>.

For this data-set, the mean is:

M = (1 + 4 + 4 + 4 + 4 + 6 + 5)/7 = 4.

Hence the standard deviation is:

$S = \sqrt{\frac{(1 - 4)^2 + (4 - 4)^2 + (4 - 4)^2 + (4 - 4)^2 + (4 - 4)^2 + (6 - 4)^2 + (5 - 4)^2}{7}} = 3.742$
