Answer:C

Step-by-step explanation:

Notice that the line is heading downward. This is a clue that it has a negative slope. Think of slope as rise over run. Rise being up or down on the y axis and run being left or right on the x axis. If we start at (0,0) and count down 3 squares and left 4 squares we can see that -3/4 is the slope.

Answer:

Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.

Step-by-step explanation:

Let [tex]x[/tex] denote the number of rafts seating 3 people and [tex]y[/tex] the number of rafts seating 5 people. The total number of rafts is 13, so [tex]x+y=13[/tex]. We can also assume that every raft is filled to the brim (it isn't stated explicitly though, but it's probably the intention of the question maker), so [tex]3x+5y=53[/tex].

It's always a good idea to put these equations under each other:

[tex]\left \{ {{x+y = 13} \atop {3x+5y=53}} \right.[/tex]

We can subtract the first equation three times from the second one to obtain [tex](3x+5y)-3(x+y) = 53 - 3(13)\\3x-3x + 5y - 3y = 53 - 39\\2y = 14\\y=\frac{14}{2} = 7[/tex]

Now, substitute this found value for [tex]y[/tex] into [tex]x+y = 13[/tex] and we see that [tex]x=6[/tex]. We are now done: Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.

x= -36

Step-by-step explanation:

Step 1

from the attachment, Mai's solving is given as

1/3 (1/2x- 9) = 1/2 (x+18)

1/6x-3= 1/2x+9

1/4x-3=9

1/4x=12

x=48

Mai's error started when he subtracted wrongly 1/2 x from 1/6x which gave him 1/4 x instead of - 1/3 x.

Solving correctly, we have that

1/3(1/2x-9) = 1/2(x+18)

1/6x -3= 1/2x+ 9

taking like terms to like terms

1/6x-1/2x= 9+3

(1-3)/6x= 12

-2/6x= 12

-1/3x= 12

multiplying both sides by -3

-1/3x X -3 = 12 X -3

x= -36

Answer:

61 is the rate at which the population changes every year

Step-by-step explanation:

Given

[tex]2000 - 61k = 48[/tex]

Required

Interpret 61

A linear equation has the form:

[tex]y = mk + b[/tex]

or

[tex]b + mk = y[/tex]

Where m is the rate

By comparison:

[tex]mk = -61k[/tex]

[tex]m = -61[/tex]

Hence, 61 represents the rate at which the population changes yearly.

The negative sign implies that the populatiin reduces

Answer:it is 0.5948

Step-by-step explanation:c

The probability that at least 1 of the selected employees will not have a college degree is 0.594776.

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,

[tex]P(x) = ^nC_x p^xq^{(n-x)}[/tex]

Where,

Given that 74% of the employees have degrees, therefore, 26% of the employees have no degree.

Now, since we want at least any one of the three people selected to have a degree. Therefore, the probability of everyone having a degree can be written as,

Probability that at least any one of the three people selected to have a degree = 1 - Probability of everyone having a degree

Now, using the binomial distribution we can write,

[tex]\text{Probability} = 1 - [^3C_0\cdot(0.26)^0 \cdot (0.74)^{(3-0)}]\\\\\text{Probability} = 1 - 0.405224 = 0.594776[/tex]

Hence, the probability that at least 1 of the selected employees will not have a college degree is 0.594776.

Answer:

Step-by-step explanation:

Given that:

a) n³

The first 4 terms are;

let assume n = 1

1³ = 1

if n = 2

2³ = 8

if n= 3

3³ = 27

if n = 4

4³ = 64

So, the sequence is 1, 8, 27, 64

The tenth term of this sequence is: 10³ = 1000

b)

2n²

if the first term is 1

then 2(1)² = 2

if n = 2

2(2)² = 8

if n = 3

2(3)² = 18

if n = 4

2(4)² = 32

So, the sequence is 1, 8, 18, 32

The tenth term will be 2(10)² = 200
