Answer:

$69.90

Step-by-step explanation:

I multiplied $65 with 0.075 (Tax percentage). I got 4.875. I rounded that up to 4.9 (Tax). Then, I added the tax with the original price ($65) and I get $69.90

Answer:

m∠ABC=42°

Step-by-step explanation:

m∠ABD=70°

⇒m∠ABD=m∠ABC+m∠CBD

⇒70°=(3x+33°)+(5x+13°)

70°=8x+46°

70°-46°=8x

24°=8x⇒x=3°

x=3°

Then,

m∠ABC=3x+33°

put x=3°, we get

m∠ABC=3×3°+33°=9°+33°

m∠ABC=42°

Answer:

Mean=20.5

standard deviation=13.28

Step-by-step explanation:

We are given six samples i.e.

36, 14, 21, 39, 11, and 2

Mean is the average of all the samples

Mean= sum of all samples/no. of samples

Mean=(36+14+21+39+11+2)/6

Mean=20.5

Standard deviation is the positive square root of variance where

variance= sum of square of samples/number of samples-(mean)²

variance=(36²+14²+21²+39²+11²+2²)/6-(20.5)²

= 596.5-420.25

= 176.25

standard deviation= √(176.25)

standard deviation= 13.28

Step-by-step explanation:

(1 point)

No, there isn't a more efficient way to solve this system.

Yes, a more efficient way is to multiply the first equation by 4, add to eliminate y, then solve for x.

Yes, a more efficient way is to multiply the first equation by −4, add to eliminate y, then solve for x.

I don't understand,please help

Answer:

f(x) = g(x) + 3

Step-by-step explanation:

Consider the y - intercept of f(x) and g(x)

g(x) has y- intercept (0, - 2)

f(x) has y- intercept (0, 1)

That is the y-intercept of f(x) is 3 units vertically up from the y- intercept of g(x)

Note that any point on f(x) is 3 units vertically up from the corresponding point on g(x)

A vertical translation is expressed as

f(x) = g(x) + 3
