Answer:

PLS HELP ASAP WILL DO BRAINLIEST IF RIGHT AND GOOD POINTS)

A wildlife refuge in South America has howler monkeys and spider monkeys. A biologist working there randomly selected eight adults of each type of monkey, weighed them, and recorded their weights in pounds.

howler monkey: {15, 16, 17, 17, 17, 17, 18, 19}

spider monkey: {12, 13, 13, 14, 14, 14, 16, 16}

(a) Calculate the mean and MAD for each type of monkey.

(b) Calculate the means-to-MAD ratio for the two types of monkeys.

when answering please seperate the answers with either 1, 2, 3 or

Answer:The mean for the howler monkeys is 17 and the MAD is 0.8571.

The mean for the spider monkeys is 14 and the MAD is 1.1429.

The means-to-MAD ratio is 2.6249.

Step-by-step explanation:

To find the mean of the howler monkeys, add all of the data values and divide by 7:

(15+16+17+17+17+17+18+19)/7 = 119/7 = 17

To find the MAD, subtract each data point from the mean; take the absolute deviation; then average these together:

(|15-17|+|16-17|+|17-17|+|17-17|+|17-17|+|17-17|+|18-17|+|19-17|)/7

=(2+1+0+0+0+0+1+2)/7=6/7 = 0.8571

Repeating these processes for the spider monkeys:

Mean:(12+13+13+14+14+14+16+16)/7 = 98/7 = 14

MAD:

(|12-14|+|13-14|+|13-14|+|14-14|+|14-14|+|14-14|+|16-14|+|16-14|)/7

=(2+1+1+0+0+0+2+2)/7 = 8/7 = 1.1429

What is the slope of the line tangent to the curve y+2 = (x^2/2) - 2siny at the point (2,0)?

Aleksandr-060686 [28]

Implicit differentiation
take the deritivive with respect to x

first
y+2=(1/2)(x^2)-2sin(y)
take deritivitive
dy/dx+0=1/2(2x)-2(cosy)dy/dx
dy/dx=x-2cosy(dy/dx)
add 2cosy(dy/dx) to both sides
dy/dx+2cosy(dy/dx) =x
undistribute dy/dx
dy/dx(1+2cos(y))=x
divide both sides by 1+2cos(y)
$\frac{dy}{dx}= \frac{x}{1+2cos(y)}$
at (2,0)
x=2
y=0

$\frac{dy}{dx}= \frac{2}{1+2cos(0)}$
$\frac{dy}{dx}= \frac{2}{1+2(1)}$
$\frac{dy}{dx}= \frac{2}{1+2}$
$\frac{dy}{dx}= \frac{2}{3}$
the slope is 2/3

Explain how you can use equivalent fractions to find the quotient of 2 3 ÷ 4.

Virty [35]

Answer:

see below

Step-by-step explanation:

2/3 ÷ 4

We use copy dot flip

The flip means make a reciprocal of the second number

2/3 * 1/4

Multiply the numerators

2*1 = 2

Multiply the denominators

3*4 =12

Put the numerator over the denominator

2/12

Simplify
