The equation y = 25x can be used to predict the height in feet, y, of the elevator after
1 seconds.
Find the height of the elevator when the time is 0 seconds.
Time (s), «
0 5 10 15
Height (ft), y

Answers

Answer 1

Answer:

y = 0 feet

Step-by-step explanation:

Given equation:

y = 25x

Where,

y = height (feet)

x = time (seconds)

25 = constant

Find the height of the elevator when the time is 0 seconds

y = 25x

y = 25(0)

y = 0 feet

Answers

Answer:

Yes

Step-by-step explanation:

Answer:

Sum: 0.78619≈0.786

Step-by-step explanation:

n=4

r=1, 2, 3, 4

r=1,2,3,4

"At least" counts up.

p=32\%=0.32

p=32%=0.32

q=1-0.32=0.68

q=1−0.32=0.68

The chance a success does NOT occur.

_{n}C_{r}p^rq^{n-r}

The probability that at most one of their six children will have that trait is 0.68

How to determine the probability?

From the question, the given parameters are

Number of children, n = 6

Probability of a child with the trait, p = 37%

The required probability that at most one will have that trait is represented as P(x ≤ 1)

This probability is calculated ;

P(x ≤ 1) = P(0) + P(1)

Where

P(x) = ⁿCₓ * pˣ (1 - p)ⁿ⁻ˣ

So, we have

P(x ≤ 1) = ⁷C₀ (37%)⁰  (1 - 37%)⁷⁻⁰ + ⁷C₁  (37%)¹  (1 - 37%)⁷⁻¹

Evaluate;

P(x ≤ 1) = ⁷C₀ * 1 * (63%)⁷ + ⁷C₁ * (37%) * (63%)⁶

So, we have;

P(x ≤ 1) = 1-0.32= 0.68

Hence, the probability is 0.68

2/3 is the simplest form

Answer:

Find the gcf, greatest common factor, of 12 and 18 and solve

Step-by-step explanation:

12: 1, 2, 3, 4, 6, 12

18: 1, 2, 3, 6, 9, 18

The gcf is 6, so divide the numerator and denominator by 6.

12 / 6 = 2

18 / 6 = 3

Therefore, 12/18, when relatively prime, is 2/3

what is the slope of the line represented by the equation y =7 - x?

Answers

Answer:

slope = -1

Step-by-step explanation:

When you put the equation into slope-intercept form (y=mx+b), where m is the slope of the line, you can see that -1 is the slope.

The slope of the line represented by the given equation is -1.

Given the following equation:

[tex]y =7 - x[/tex]    ...equation 1.

To determine the slope of the line represented by the given equation:

Mathematically, the standard form of an equation of line is given by the formula;

[tex]y=mx+b[/tex]   ....equation 2.

Where:

x and y are the points.m is the slope.b is the intercept.

Equating the two equations, we have:

[tex]y = mx+b = 7-x[/tex]

Comparing eqn 1 and eqn 2, we can deduce that the slope is -1.

The relationship between income (I), in dollars, and the time (h), in hours, for 2 different jobs is represented. Compare the hourly rates of Job A and Job B.

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete. However, I will solve using the following assumptions.

Job A:

[tex]y = 2x + 5[/tex]

Job B

[tex]\begin{array}{cccccc}x & {1} & {2} & {3} & {4} & {5} \ \\ y & {6} & {10} & {14} & {18} & {22} \ \end{array}[/tex]

The first step is to calculate the rate of Job B using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where:

[tex](x_1,y_1) = (1,6)[/tex]

[tex](x_2,y_2) = (2,10)[/tex]

So, we have:

[tex]m = \frac{10 - 6}{2 - 1}[/tex]

[tex]m = \frac{4}{1}[/tex]

[tex]m = 4[/tex]

So, the hourly rate of job B is $4/hr

For Job A:

[tex]y = 2x + 5[/tex]

A linear equation has the form:

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

Where m is the rate

By comparison:

[tex]m = 2[/tex]

So, the hourly rate of Job A is $2/hr

Comparing both rates, we can draw the following conclusions;

The hourly rate  of Job A is greater than the hourly rate of Job BThe hourly  rate of Job A is twice the hourly rate of Job B.

Answer:

x=1 and x=3

Step-by-step explanation:

When you factor it you get (x-1) and (x-3) then you subtract the 1 and 3 to the other side which is why the answer is positive.  

Answer:

x = 1, x = 3

Step-by-step explanation:

Equate the expression to zero, that is

x² - 4x + 3 = 0 ← in standard form

(x - 1)(x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 3 = 0 ⇒ x = 3

Rani deposited AED 12000 for 3 years at the rate of 5 percent per annum. Calculate the simple interest and amount at the end of the 3rd year

Answers

Answer:

the principal and the amount is 1,800 and 13,800 respectively

Step-by-step explanation:

The computation of the simple interest and amount for the end of the 3rd year is shown below:

Simple interest is

= Principal × rate of interest × time period

= 12,000 × 5% × 3 years

= 1,800

Now the amount is

= 12,000 + 1,800

= 13,800

hence, the principal and the amount is 1,800 and 13,800 respectively
