Drag each number to show whether or not it is a solution to the inequality.
Inequality: 42x - 12 ≤ 24

( 10, 9 , -5, 12.5 , 0 )

Solution to the inequality
42x - 12 ≤ 24

NOT a solution to the inequality 42x - 12 ≤ 24​

Answers

Step-by-step explanation:

A linear inequality is given to us and we need to drag each number to show whether or not it is a

solution to the inequality .The given inequality to us is ,

[tex]\bf\implies 4x - 12 \leq 24 \\\\\bf\implies 4x \leq 24+12 \\\\\bf\implies 4x \leq 36 \\\\\bf\implies x \leq \dfrac{36}{4}\\\\\bf\implies x\leq 9\\\\\bf\implies \boxed{\red{\bf x \in [9,-\infty ) }}[/tex]

Hence , x can have all values less than or equal to 9. That is x E [ 9 , -∞ ) .

Options provided to us are ,

10 6 9(-5) 12.50

Hence values less than or equal to 9 are 9 , 6 , (-5) and 0 .

The ratio of teachers to students on a field trip to New York City is 2 to 9. If there are 243 students on the trip,

Answers

Answer:

54 teachers

Step-by-step explanation:

Step one:

given data

The ratio of teachers to students on a field trip to New York City is 2 to 9.

That is the ratio is 2:9

We are told that there are 243 students

Required

We want to find the number of teachers

Step two:

Applying the part to part method we have

let the number of teachers be x

2/9= x/243

cross multiply we have

9x= 243*2

9x= 486

divide both sides by 9

x= 54

Hence there are 54 teachers

If the radius of a circle is 9 cm, what is the area of the circle?
The diameter of the circle is 100 cm what is the circumference of the circle? (Use = 3.14.)

Answers

Step-by-step explanation:

the formula for the area of a circle is

πr²

plug 9 in for r (radius) to get

3.14 (81) = 254.34 cm² as our area

the circumference is equal to πd , with π being pi and d being diameter.

the circumference is then 3.14(100) = 314cm

In a certain breed of cattle, the length of gestation has a mean of 284 days and a standard deviation is 5.5 days. One length of gestation had a z-score of -1.70. Which of the following sentences best interprets the z-score?
A. The length of this gestation period was longer than the mean length of gestation periods by 1.7 days.
B. The length of this gestation period was shorter than the mean like the gestation periods by 1.7 days.
C. The length of this gestation period was longer than the mean length of gestation periods by 1.7 standard deviations.
D. The length of this gestation period was shorter than the mean length of gestation periods by 1.7 standard deviations.

Answers

Answer:

The statement that best interprets the z-score is;

D. The length of the gestation period was shorter than the mean length of gestation period by 1.7 standard deviations

Step-by-step explanation:

The given parameters are;

The length of the gestation period of the cattle breed = 284 days

The standard deviation = 5.5 days

The z-score of one length of gestation period was z = -1.70

The formula for finding the z-score, z is presented as follows

[tex]Z=\dfrac{x-\mu }{\sigma }[/tex]

Where;

x = The observed value for the gestation period

μ = The sample mean length for the gestation period = 284

σ = The gestation period standard deviation = 5.5

When Z = -1.70, we have;

[tex]-1.70 =\dfrac{x-\mu }{\sigma }[/tex]

∴ x - μ = -1.7 × σ

∴ x is shorter than μ by 1.7×σ

Therefore, the length of the gestation period, x, was shorter than the mean length of gestation period, μ, by 1.7 standard deviations, σ.

Answer:

D. The length of the gestation period was shorter than the mean length of gestation period by 1.7 standard deviations

Step-by-step explanation:

A florist was looking at her flower order. The ratio of roses to sunflowers was 4 to 9. When she was done, she realized there were 65 MORE sunflowers than roses. How many of each flower was there?

Answers

Answer:

[tex]52[/tex] roses and [tex]117[/tex] sunflowers

Step-by-step explanation:

Since the ratio of roses to sunflowers is [tex]4:9[/tex], we can represent how many there are of each as [tex]4x[/tex] and [tex]9x[/tex], respectively. We know that there are [tex]65[/tex] more sunflowers than roses, so we can set up the following equation to solve for [tex]x[/tex]:

[tex]4x+65=9x[/tex]

Solving for [tex]x[/tex], we get:

[tex]4x+65=9x[/tex]

[tex]4x+65-4x=9x-4x[/tex] (Subtract [tex]4x[/tex] from both sides of the equation to isolate [tex]x[/tex])

[tex]65=5x[/tex] (Simplify)

[tex]5x=65[/tex] (Symmetric Property of Equality)

[tex]\frac{5x}{5}=\frac{65}{5}[/tex] (Divide both sides of the equation by [tex]5[/tex] to get rid of [tex]x[/tex]'s coefficient)

[tex]x=13[/tex] (Simplify)

Therefore, since [tex]x=13[/tex], we know that there are [tex]4x=4*13=52[/tex] roses and [tex]9x=9*13=117[/tex] sunflowers. Hope this helps!

At the beginning of the day, the sum of the stocks in the Dow Jones was
$10,335.24. At the end of the day, the sum of the stocks in the Dow Jones
was $10,215.78. What was the rate of change of the Dow Jones on this
particular day?

Answers

Answer:

- 1.15585%

Step-by-step explanation:

Given that:

Sum of stock at beginning = $10,335.24

Sum of stock at the end of the day = $10,215.78

Rate of change of the Down Jones on that day :

The change in price on the day:

Ending - Beginning

10,215.78 - 10,335.24 = −119.46

The rate if change is thus ;

(Change in price / beginning stock price) * 100%

(-119.46 / 10,335.24) * 100%

-0.0115585 * 100%

- 1.15585%

Use the graph shown. State the number of real zeros of the function.

Answers

Answer:

Option B

Step-by-step explanation:

Zeros of a function are defined by the values of x at y = 0,

In other words, x-intercepts of a function graph are the zeros of the function.

Real zeros means graph should intersect or touch the x-axis.

If it is imaginary, the graph will have no x-intercept.

From the graph attached,

There are 3 points where the graph intersects the x-axis.

Therefore, the function will have 3 real zeros.

Option B is the answer.
