Answer:

EF = 3.6 is the answer.

Step-by-step explanation:

In the given picture coordinates of the endpoints of EF has been given and we have to calculate the length of the segment EF.

As we know when coordinates of two points are given and we have to calculate the distance between them we use the formula

Distance EF = √[(x - x')²+(y - y')²]

Here (x, y) and (x', y') are (-3, 1) and (-1, -2).

So distance EF = √(-3+1)²+(1+2)² =√(-2)²+(3)² = √(4 + 9) = √13

EF = 3.60

So the answer is 3.6

Find the area of a circle with a Radius = 4 ft. Use 3.14 for and round to 2 decimal places.

bagirrra123 [75]

Answer:

50.24 ft^2

Step-by-step explanation:

Well formula for area of a circle is pi(radius)^2

so the radius is 4 so you square that it’ll be 16

then do 16(3.14)

you’ll get 50.24

Solve the equation<br>4(y-3)=13

I am Lyosha [343]

Step-by-step explanation:

$4(y - 3) = 13 \\ \\ \therefore \: 4y - 4 \times 3 = 13 \\ \\ \therefore \: 4y - 12 = 13\\ \\ \therefore \: 4y = 13 + 12 \\ \\ \therefore \: 4y = 25 \\ \\ \therefore \:y = \frac{25}{4} \\ \\ \therefore \:y = 6\frac{1}{4}$

IQ test scores are standardized to produce a normal distribution with a mean of = 100 and a standard deviation of = 15. Find the

mixas84 [53]

Answer:

0.01

Step-by-step explanation:

Using the z score formula

z = (x-μ)/σ,

where x is the raw score = 135

μ is the population mean = 100

σ is the population standard deviation = 15

z = 135 - 100/15

z = 2.33333

P-value from Z-Table:

P(x<135) = 0.99018

P(x>135) = 1 - P(x<135)

P(x > 135) = 1 - 0.99018

= 0.0098153

Approximately to 2 decimal places

= 0.01

Therefore, the proportion of the population for the following IQ score of 135 is 0.01
