We get the cumulative frequency as:

We are given the data:

Daily Low(°F) Frequency

35 - 39 3

40 - 44 4

45 - 49 6

50 - 54 9

55 - 59 7

60 - 64 7

65 - 69 1

We have to find the cumulative frequency of the data.

We will do this by adding the data values of previous interval.

Daily Low(°F) Frequency cumulative frequency

35 - 39 3 3

40 - 44 4 7

45 - 49 6 13

50 - 54 9 22

55 - 59 7 29

60 - 64 7 36

65 - 69 1 37

Therefore, we get the cumulative frequency as:

Ginny’s favorite cookie recipe requires 1 1/2 cups of sugar to make 24 cookies. How much sugar does Ginny need to make 36 of the

Delicious77 [7]

Ginny needs $2\frac{1}{4}$ cups of sugar to make 36 cookies.

Step-by-step explanation:

Given,

Sugar cups required for 24 cookies = $1\frac{1}{2}=\frac{3}{2}\ cups$

Ratio of sugar cups to cookies = $\frac{3}{2}:24$

Let,

x be the number of cups needed for 36 cookies.

Ratio of sugar cups to cookies = $x:36\\$

Using proportion;

Ratio of sugar cups to cookies :: Ratio of sugar cups to cookies

$\frac{3}{2}:24::x:36$

Product of mean = Product of extreme

$24*x=\frac{3}{2}*36\\24x=54$

Dividing both sides by 24

$\frac{24x}{24}=\frac{54}{24}\\x=\frac{9}{4}\\x=2\frac{1}{4}$

Ginny needs $2\frac{1}{4}$ cups of sugar to make 36 cookies.

I need this fast yal. i am willing to give brainly

andreyandreev [35.5K]

Answer:

The answer is

y = 6x + 43

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

The original line is y = 6x + 1

Comparing with the general equation above

Slope = 6

Since the lines are parallel their slope are also the same

Slope of parallel line = 6

The equation of the line using point (-7,1) and slope 6 is

We have the final answer as

y = 6x + 43

Step-by-step explanation:

Which rule can you use to find the nth term of an arithmetic sequence in which the common difference is 5 and a12 = 63?

iren2701 [21]

Tn = a + (n-1)d

when n = 12, tn = 63

63 = a + (12-1)*5

a = 63 - 55 =8

tn or an
= 8 + (n-1) 5

= 3 + 5n

Hope this helps

Nari says, "The sum of 10 and one-third of a number is 25." She uses the bar model to write an equation to represent her

Mariana [72]

Answer:

$25=10+\frac{1}{3}n$ .

Step-by-step explanation:

It is given that the sum of 10 and one-third of a number is 25.

Let as consider n be the unknown number.

One-third of a number $=\frac{1}{3}n$

Sum of 10 and one-third of a number $=10+\frac{1}{3}n$

The sum of 10 and one-third of a number is 25. It can be written as

$25=10+\frac{1}{3}n$

Therefore, the required equation is $25=10+\frac{1}{3}n$ .

What is the solution for the equation -15=5(3y-10)-5y

marissa [1.9K]

Answer:

$\Large\boxed{\sf{y=\dfrac{7}{2} }}$

Step-by-step explanation:

Isolate the variable of y from one side of the equation.

-14=5(3y-10)-5y

First, switch sides.

$\sf{5\left(3y-10\right)-5y=-15}$

Use the distributive property.

DISTRIBUTIVE PROPERTY:

A(B-C)=AB-AC

5(3y-10)

Multiply by expand.

5*3y=15y

5*10=50

15y-50-5y

15y-5=10y

= 10y-50

10y-50=-15

Add by 50 from both sides.

10y-50+50=-15+50

Solve.

10y=35

Then, you divide by 10 from both sides.

10y/10=35/10

Solve.

Divide the numbers from left to right.

35/10=7/2

y=7/2

Divide is another option.

7/2=3.5

$\Longrightarrow: \boxed{\sf{y=\dfrac{7}{2}}}$

Therefore, the correct answer is y=7/2.

I hope this helps. Let me know if you have any questions.
