The single digit to the left of the vertical line is the tens units, the numbers to the right are the ones.

The scores above 64, would be 65, 73, 74, 77, 87, 88, 91, 93, 93, 97, 99, 99

A total of: 12 scores.

Answer:

Step-by-step explanation:

A stem-and-leaf plot is a format used to present quantitative data, where stem values are tenths and leaf values are units. For example, in this case, the first value is 32, 3 tenths (stem) and 2 units (leaf). So, each value in the stem colum is tenth and each number in leaf colum represents unit of those tenths.

Now, to find all numbers above 64, we observe the number 6 in the stem colum, then we count all leaf numbers in that level and above.

Observe that there are 13 values when 6 as tenth, but the first one doesn't count because its unit is 4, and we need all numbers ABOVE 64.

Therefore, there are 12 numbers above 64 which are:

65, 73, 74, 77, 87, 88, 91, 93, 93, 97, 99, 99.

Lisa makes a cherry pie and an apple pie. She cuts the cherry pie into six equal wedges and she cuts the apple pie into eight eq

ale4655 [162]

Both the pies at first have 360* as their initial complete angles.

The Cherry Pie is cut into 6 parts equal and the angular width of each piece will be 360/6=60*...therefore, each piece is 60*.

the Apple Pie is cut into 8 parts and the angle of each piece would be 360/8=45*...therefore, each piece is 45*.

Now the angular difference between the pieces of the 2 pies is 60*-45* = 15*.

Therefore the Cherry pie's piece is 15* greater than the Apple pie's piece.

Given the functions f(x) = x² – 8 and g(x) = 4-x, determine the equation for the combined function

ElenaW [278]

Answer:

$y=x^2+x-12$

Step-by-step explanation:

f(x) = x² – 8 and g(x) = 4-x

y=f(x) - g(x)

y=(x² – 8) - (4-x)

$y=x^2-8-4+x\\y=x^2+x-12$

Find the value x and write the property used here.

Serga [27]

Step-by-step explanation:

Soln,

Here,

45°+65°+y(let)=180°[ being a triangle]

or,110°+y=180°

or,y=180°-110°

so,y=70°

Now,

x=?

so,

x+y=180°[being straight angle]

or,x+70°=180°

or,x=180°-70°

x=110°

THEREFORE,x=110°

solved!

Answer:

GCF = 5

Step-by-step explanation:

15x² - 10x + 5

x is not contained in all 3 terms thus is not a factor

15 has factors 1, 3, 5, 15

- 10 has factors ± 1, ± 2, ± 5 , ± 10

5 has factors 1, 5

The common factors are 1, 5

Then GCF = 5
