SOMEONE PLSLPLSSLSLS HELP ITS JUST 3 QUESTIONS BRO PLEASE ITS SO CONFUSING ILL BRAINLIST.

Vinil7 [7]

Step-by-step explanation:

a) Perimeter is equal to 2w + 2L

2(3x + 4) + 2(x + 3)

6x + 8 + 2x + 6

8x + 14

b) Put 5 in x's place

8×5 + 14

40 + 14

54

c) Area = (3x + 4) * (x + 3)

Put 4 in x's place

(3×4 + 4) * (4 + 3)

12 + 4 * 7

16 * 7

The original pulse rates are measure with units of "beats per minute". what are the units of the corresponding z scores? choo

posledela

the complete question is

Pulse rates of women are normally distributed with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per minute. The original pulse rates are measure with units of "beats per minute". What are the units of the corresponding z scores? Choose the correct choice below.

A. The z scores are measured with units of "beats per minute."

B. The z scores are measured with units of "minutes per beat."

C. The z scores are measured with units of "beats."

D. The z scores are numbers without units of measurement.

we know that

A z-score is the number of standard deviations from the mean a data point is. But more technically it’s a measure of how many standard deviations below or above the population mean a raw score is

The z scores are numbers without units of measurement

therefore

the answer is the option D

Find the following measure for this figure.

ss7ja [257]

Answer: last option (5π√146 units²)

Step-by-step explanation:

To solve the exercise you must apply the formula for calculate the lateral area of a cone, which is shown below:

$LA=r*L*\pi$

where r is the radius but L is the slant height.

As you can see in the figure attached:

$r=5$

But you need to find the slant height with the Pythagorean Theorem (L would be the hypotenuse):

$L=\sqrt{11^2+5^2}=\sqrt{146}$

Substitute into the formula, then:

$LA=(5)(\sqrt{146})\pi=5\pi\ \sqrt{146$ units²

What the factors of 40 with a sum of -22? *

Andru [333]

Answer:

Why is 90 the sum of all factors of 40, including 40? The factors of the number 40 are: 1, 2, 4, 5, 8, 10, 20, 40. If you add them up, you will get the total of 90.

Step-by-step explanation:

2. Given the points A, B, C, D, calculate:

(a) the angle B of the triangle ABC

(b) the area of the triangle ABC

(c) the median BE of the triangle ABC

(d) the height AH of the triangle ABC

(e) the volume of tetrahedron ABCD

(f) the point E so that ABCE is a parallelogram.

A(-1, 2, -3), B(4, -1, 0), C(2, 1, -2), D( 3,4,5)

99 POINTS, NEED HELP WITH ALGEBRA

Tanya [424]

1 is in picture above.

2.

$average \: rate = \frac{f(4) - f(1)}{4 - ( - 1)} = \frac{5}{4 - ( - 1)} = 1$

3. In the picture...

4. In the picture...

5. Parts A and B are true.

6.

$average \: rate = \frac{f(0) - f( - 10)}{0 - ( - 10)} = \frac{( - 6) - 184}{0 - ( - 10)} = \frac{ - 190}{10} = - 19$

7. The axis symmetry equation of

$y = a {x}^{2} + bx + c$

is

$x = \frac{ - b}{2a}$

So it would be x=-3/4

8.

$y = {(x - 6)}^{2} + 10$

T=(6, 10) vertex coordinates...
