lina2011 [118]

Answer: First and last option

The birds began 1320 miles from the equator.

The birds are flying toward the equator at a rate of 60 mph.

Step-by-step explanation:

Note that the function f(x) is a linear function.

$f (x) = - 60x + 1320$

If x represents the number of hours and f(x) represents the distance from the equator, then x = 0 means that the first hour has not yet elapsed.

When x = 0 then:

$f (0) = -60 * 0 +1320\\f (0) = 1320$ .

This means that the initial distance at which the birds of the equator are located is 1320 miles.

Then when x = 1 then:

$f (x) = -60 * 1 + 1320\\f (x) = -60 +1320$

When x = 2 then:

$f (x) = -60 * 2 + 1320\\f (x) = -120 +1320$

As x increases by one unit then the distance of the birds to the equator decreases by 60 miles. This means that birds travel at a speed of 60 miles per hour

Answer:

D. $A\subset \mathbb{R}\times\mathbb{R}.$

Step-by-step explanation:

Consider the set

$A=\left\{(2,3),\ (5,1),\ (-3,-2),\ (0,3)\right\}$

This set consists of four ordered pairs.

The first numbers in these pairs are $2,\ 5,\ -3,\ 0.$ These numbers are integer numbers (not natural, because -3 is negative).

The second numbers in these pairs are $3,\ 1,\ -2,\ 3.$ These numbers are integer numbers too (not natural, because -2 is negative).

Options contain only natural and real sets, so, the first and the second numbers are real numbers and

$A\subset \mathbb{R}\times\mathbb{R}.$

Leokris [45]

Answer:

The mean carrying load of the beams tested is 908.7 pounds per square foot

Step-by-step explanation:

1. Data class 1: 860-879

Midpoint 1: M1=(860+879)/2=1,739/2→M1=869.5

Number of values in data class 1: n1=2

2. Data class 2: 880-899

Midpoint 2: M2=(880+899)/2=1,779/2→M2=889.5

Number of values in data class 2: n2=5

3. Data class 3: 900-919

Midpoint 3: M3=(900+919)/2=1,819/2→M3=909.5

Number of values in data class 3: n3=10

4. Data class 4: 920-939

Midpoint 4: M4=(920+939)/2=1,859/2→M4=929.5

Number of values in data class 4: n4=6

5. Data class 5: 940-959

Midpoint 5: M5=(940+959)/2=1,899/2→M5=949.5

Number of values in data class 5: n5=1

Mean=Sum(Mi*ni)/Sum(ni)

Mean=(M1*n1+M2*n2+M3*n3+M4*n4+M5*n5)/(n1+n2+n3+n4+n5)

Mean=(869.5*2+889.5*5+909.5*10+929.5*6+949.5*1)/(2+5+10+6+1)

Mean=(1,739+4,447.5+9,095+5,577+949.5)/(24)

Mean=(21,808)/(24)

Mean=908.6666666

Rounding to one decimal place:

Mean=908.7

May be I’m wrong, but I think all you have to do is 8x8x8= which is 512

Take your five twelve and divide by 3.14 and that leaves 163.057!

Hope this helps you.
