Answer:

All false.

Step-by-step explanation:

The ratio is 3:4.

For every 3 girls, there are 4 boys.

If a class has 7 people, 3 are girls and 4 are boys.

Hence the fraction of boys is 4/7 and girls are 3/7.

Therefore, a and b are False.

The number of boys in the class cannot be 6. If the number of boys is 6, then the number of girls must be 4.5 to maintain the 3:4 ratio, but there cannot be half a girl. So, c is also false. d) the number of pupils in the class is 12. To maintain a 3:4 ratio, the number of pupils in the class must be in multiples of 7. Hence, d is also false.

Answer:

Use properties of log:

Statements:

log₃ (vw/x) = log₃ vw - log₃ x = log₃ v + log₃ w - log₃ x

log₄ n + 3 log₄ m = log₄ n + log₄ m³= log₄ (nm³)

1/3(log₂ c + log₂ d) - 4 log₂ e = log₂ c[tex]^{1/3}[/tex] + log₂ d[tex]^{1/3}[/tex]  - log₂ e⁴= log₂ (c[tex]^{1/3}[/tex] d[tex]^{1/3}[/tex] /e⁴)

Answer:

its 216 cubic feet.

Step-by-step explanation:

6x6x6 is 216

Answer:

1 1/30

Explanation:

we know that 0.3 (recurring) is equivalent to ⅓. thus, we can find 0.03 (recurring) by adding an extra decimal behind the denominator to get 1/30.

accounting for the 1, we can now get 1 1/30.

Answer:

this question doesnt make a lot of sence but i think its 90

Step-by-step explanation:

45+45 = 90

since ats a triangle 180-90 = 90

also the right angle with the red aquare is 90 degrese so i its 90

Answer:

Its a vertical angel, x + 45 =90.

Step-by-step explanation:

Not a robot! I don't think.

Y in the beginning goes up to 3.

Y in the end goes down to -2 before shooting back up in an infinite sense.

Increasing: The beginning and the end the line on the graph. (Also the jump in the middle, the round part.)

Decreasing: The middle of the graph. (The jump, downward slope.)

Constant, Y at the near end going in a straight line from 9-12 at a -2.

End behavior: Decide for yourself. Is the line going up without fault at the end an appearing continuous or a discontinuous line?

Answer:

End Behavior:

x⇒-8,y⇒-∞

x⇒∞,y⇒∞

(-∞,1},{3,5},{12,∞)

{1,3},{5,9}

(9,12)

Answer:

40 miles , 1 hour 30 mins

Step-by-step explanation:

(a)

His visit to Nicola is indicted by the horizontal part of the graph.

Using the vertical ( distance ) axis , this shows 40 miles

(b)

Using the horizontal ( time ) axis

The left side of the horizontal red line shows 10.00

The right side shows 11.30

Then 11.30 - 10.00 = 1 hour 30 minutes

Answer:

x= -11

Step-by-step explanation:

1/2(x-8)=3/2x+7

distribute

1/2x-4 = 3/2x+7

subtract 1/2x from both sides

1/2x cancels out

-4 = 1x+7

subtract 7 from both sides

-11 = 1x (1x is the same as "x")

Answer:

x=-11

Step-by-step explanation:

The solution to the equation is -11.

First I set up the equation.

1/2(x-8)=3/2x+7

Next, I simplified the equation. 1/2x-4=3/2x+7.

Then, I added 4 to both sides. 1/2x=3/2x+11.

Next, I subtracted 3/2x on both sides. -1x=11.

Then, I divided -1 on both sides, so I would have x by itself.

x=-11.

In conclusion, the solution to the equation is x= -11.

To check to make sure this is the correct answer, I put -11 into the x values of the equation.

1/2(-11-8)=3/2(-11)+7

Both sides of the equation equal -19/2.

Answer:

x = 105

Step-by-step explanation:

Let the unknown (missing) number be x.

In Mathematics, quotient simply means division i.e to divide a number by another.

Thus, translating the word problem into an algebraic expression, we have;

[tex] \frac{x}{7} - 5 = 10 [/tex]

To find the value of x, we would simplify the algebraic expression.

[tex] \frac{x}{7} = 10 + 5 [/tex]

[tex] \frac{x}{7} = 15 [/tex]

Cross-multiplying, we have;

[tex] x = 15 * 7 [/tex]

x = 105

Answer:

Step-by-step explanation:

That would be 23 - 50, or -27.

Answer:

Step-by-step explanation:

i got it wrong and it showed this instead

a-0.23125

b-720

The required,
(a) The experimental probability that a randomly selected worker at that company walks to work is approximately 0.23125 or 23.125%.

(b) we can predict that about 762 of the 3300 workers at the company walk to work.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

a. The experimental probability of a randomly selected worker at that company walking to work can be calculated as the ratio of the number of workers who walk to work to the total number of workers surveyed:

Experimental probability = Number of workers who walk to work / Total number of workers surveyed

Experimental probability = 37 / 160

Experimental probability = 0.23125 or 23.125%

Therefore, the experimental probability that a randomly selected worker at that company walks to work is approximately 0.23125 or 23.125%.

b. To predict about how many of the 3300 workers at the company walk to work, we can use the experimental probability calculated above to estimate the number of workers who walk to work out of the total number of workers:

Number of workers who walk to work = Experimental probability x Total number of workers

Number of workers who walk to work = 0.23125 x 3300

Number of workers who walk to work = 762.375

Therefore, we can predict that about 762 of the 3300 workers at the company walk to work.

Answer: 4

Step-by-step explanation:

Formula:

logb(x) = y, if by = x

Input:

x = 256

b = 4

Solution:

y = log4 256

= log4 44

= 4 log4 4 = 4 x 1

log4 256 = 4

Answer:a)

a) 68%

b) 44%
