5 0

Answer:

49

Step-by-step explanation:

There is no answer choices so I can't really select an answer so I just provided my own. If you do provide the answer choices and my answer is wrong tell me and I will gladly change it. Anyways my explanation is since there are 7 days in a week and she collected 7 leaves for a week you would find this answer out by multiplying 7 by 7. 7x7=49

Lisa has a scholarship that pays 75% of her tuition for all four years she attends college. What is the total amount the scholar
12345 [234]
Since you're given the total cost per year (12,000) you multiply it by 4 so that you get the total amount for the four years. e.g. (4 x 12,000) = 480,000
Now you calculate the 75% from this amount because we want to obtain the amount of money the scholarship is worth. That is 480,000 x 75% = 360,000
or 480,000 x 0.75 = 360,000
So, the scholarship is of 360,000

I don’t know the answer or how to do this, help!
makvit [3.9K]

Answer:

B.

Step-by-step explanation:

y = x^2 - x - 12

y = (x-4)×(x+3) that means x it either 4 or -3

y = x + 3

for x = 4 ➡ y = 3+4 ➡7

for x = -3 ➡ y = -3 + 3➡0

(the answer key is most probably faulty there's no way for y to be 0 in both scenarios)

What is the slope for (-2,3) (6,-1)
TiliK225 [7]

Answer:

Step-by-step explanation:

The slope of the line between two points can be found with the following equation:

\frac{y_{2} - y_{1}}{x_{2} - x_{1}}

Plugging in the points (x_{1}, y_{1}) and (x_{2}, y_{2}) from the problem statement, we get the following:

\frac{-1 - 3}{6 - (-2)

\frac{-4}{8}

\frac{-1}{2}

About​ ______% of the area is between z= -1 and z= 1 ​(or within 1 standard deviation of the​ mean)? How do you solve this?
nexus9112 [7]

Answer:

68%

Step-by-step explanation:

<em><u>68-95-99.7% Rule:</u></em>

<em><u /></em>

This is the empirical rule which is used to remember the percentage of values that is within a band of the mean. We say:

  • 68% of the data fall within 1 standard deviation of the mean
  • 95% of the data fall within 2 standard deviation of the mean, and
  • 99.7% of data falls within 3 standard deviations of the mean

Clearly, from the empirical rule, we see that about 68% of the area is between z = -1 and z = 1 (or within 1 standard deviation of the mean)
