Answer:

38 in²

Step-by-step explanation:

divide the shape into a rectangle and a triangle (see attached)

Area of Rectangle = 8 x 4 = 32 in²

Area of Triangle = (1/2) x 4 x 3 = 6 in²

Total area

= Area of Rectangle + Area of Triangle

= 32 + 6

= 38 in²

use the frequency table to find the probability of five or more responses received to this week's newspaper editorials.
aniked [119]

Answer:

option-B

Step-by-step explanation:

we have to find probability for 5 or more

Calculation of p(5):

number of editorials having 5 responses is 16

total number of editorials =200

so, we can find probability

p(5)=\frac{16}{200}

p(5)=\frac{2}{25}

Calculation of p(=>6):

number of editorials having 6 or more  responses is 6

total number of editorials =200

so, we can find probability

p(=>6)=\frac{6}{200}

p(=>6)=\frac{3}{100}

Calculation of p(=>5):

we can use formula

p(>=5)=p(5)+p(=>6)

we can plug values

p(=>5)=\frac{2}{25}+\frac{3}{100}

p(\geq5 )=\frac{11}{100}

p(\geq5 )=0.11

so, answer is option-B

Which equation represents a line that is parallel to the line whose equation is 2x + 3y =12
STALIN [3.7K]

Answer:

Choose an equation that has this same slope or the same coefficients of x and y - 2x + 3y.

Step-by-step explanation:

Parallel lines are lines which do not intersect. As a result they have the same slope. The line here is 2x + 3y = 12 which can be rearranged into slope intercept form to find the slope.

2x + 3y = 12

3y = 12 - 2x

y = 4 - 2/3 x

The slope of the line is -2/3. Choose an equation that has this same slope or the same coefficients of x and y - 2x + 3y.
