What is the slope of a line perpendicular to this line?

Step-by-step explanation:

For a line to be parallel, it needs to have same slope so the slope is -1/2 for parallel.

The slope for perpendicular is the negative reciprocal so 2.

The weight of oranges growing in an orchard is normally distributed with a mean weight of 6.5 oz. and a standard deviation of 1.5 oz. Using the empirical rule, determine what interval would represent weights of the middle 99.7% of all oranges from this orchard.

Answers

Add 3 standard deviations above and below the mean to get the range in which 99.7% of the data in a normal distribution will fall
6.5 + 4.5 = 11
6.5 - 4.5 = 2
So 2 to 11 ounces would be the interval

SAT QUESTION!!!


Jayden has been reading a 275-page book for English class. On average, he has read about 10 pages in 15 minutes. With a deadline looming, Jayden realizes that he won't finish in time unless he skims through the rest of the book. If he skims the book, he can cover 15 pages in 10 minutes. If it takes Jayden 5 hours and 50 minutes to finish the book (reading and skimming combined), how many pages did Jayden have to skim through?

WITH STEPSSS

Answers

Step-by-step explanation:

Let x be the number of pages that were skimmed through.

Time taken to skim through = 10 * (x/15) = 2/3 x min.

Time taken to read through = 15 * [(275-x)/10] = 1.5(275-x) min.

We have 2/3 x + 1.5(275-x) = 350.

Therefore 412.5 - 5/6 x = 350 and x = 75.

Answer:8pages

Step-by-step explanation:

10minutes/350minutes×275=7.85~8pages

In a certain Algebra 2 class of 27 students, 18 of them play basketball and 16
of them play baseball. There are 3 students who play neither sport. What is
the probability that a student chosen randomly from the class plays
basketball or baseball?

Answers

Answer:

The probability is 0.89 or 89%

Step-by-step explanation:

Probability

There are n=27 students in a certain Algebra 2 class. 18 out of them play basketball and 16 of them play baseball.

We also know 3 students play neither sport. This leaves 27-3=24 students playing sports.

The probability that a randomly chosen student plays basketball or baseball is:

[tex]\displastyle p=\frac{24}{27}[/tex]

Simplifying:

[tex]\displastyle p=\frac{8}{9}=0.89[/tex]

The probability is 0.89 or 89%

Answer:

x=2<br/>y=1

Step-by-step explanation:

\left\{ \begin{array} { l } { 4 x + y = 9 } \\ { 3 x - 2 y = 4 } \end{array} \right.

4x+y=9,3x-2y=4

4x+y=9

4x=-y+9

x=\frac{1}{4}\left(-y+9\right)

x=-\frac{1}{4}y+\frac{9}{4}

3\left(-\frac{1}{4}y+\frac{9}{4}\right)-2y=4

-\frac{3}{4}y+\frac{27}{4}-2y=4

-\frac{11}{4}y+\frac{27}{4}=4

-\frac{11}{4}y=-\frac{11}{4}

y=1
