x(say) 12

Now, using direct variation

[tex] \frac{2}{x} = \frac{3}{12} \\ \frac{2}{x} = \frac{1}{4} \\ x = 2 \times 4 \\ x = 8[/tex]

Answer:

0.972x

Step-by-step explanation:

x - 0.1x + 0.08(0.9x)

Converting percentages to decimals has you divide the percentage by 100.

So our first equation is full price minus a tenth of that price, leaves you with nine tenths, right? Then we multiply that nine tenths by 8 percent, which is 8 hundredths.

0.9x + 0.072x = 0.972x

Answer:

3/8

Step-by-step explanation:

First, find the number of bracelets she's able to make with her string. She has 5/8 of a yard and uses 1/5 per bracelet. To divide the number of yards she has by the number she uses, multiply 5/8 by the reciprocal of 1/5 (5/1).

5/8 * 5/1 = 25/8

25/8 is 3.12500, which is the number of bracelets she can make. It rounds down to 3 since she can't make 0.12500 bracelets.

Now, find how many charms she used. 3 bracelets * 12 charms each is 36 charms in total.

So she used 36/96 of her charms. This can be simplified to 3/8.

Answer:

37/96 hazel has

Step-by-step explanation:

1/5 times 12=60

so Hazel uses 1 yardd for 60 charms, so for 5/8 yard Hazel would use 5/8×60=37.5.

since Hazel isn't able to use a fraction of a charm, she would use 37 charms

37/96 Charms Hazel has

I think it's 462.99, rounded it's 463

[tex] {6}^{3} \times {7}^{3} = {(6 \times 7)}^{3} = {42}^{3} [/tex]

Step-by-step explanation:

When two or more quantities have the same exponents, their bases can be multiplied together.

Answer:

[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]

[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]P(Red) = \frac{2}{7}[/tex]

[tex]P(Blue) = \frac{3}{14}[/tex]

Required

Which completes the model

Let the remaining probability be x.

Such that:

[tex]P(Red) + P(Blue) + x = 1[/tex]

Make x the subject

[tex]x = 1 - P(Red) - P(Blue)[/tex]

So, we have:

[tex]x = 1 - \frac{2}{7} - \frac{3}{14}[/tex]

Solve

[tex]x = \frac{14 - 4 - 3}{14}[/tex]

[tex]x = \frac{7}{14}[/tex]

[tex]x = \frac{1}{2}[/tex]

This mean that the remaining model must add up to 1/2

[tex](a)\ P(Green) = \frac{2}{7} ; P(Yellow) = \frac{2}{7}[/tex]

[tex]P(Green) + P(Yellow)= \frac{2}{7} + \frac{2}{7}[/tex]

Take LCM

[tex]P(Green) + P(Yellow)= \frac{2+2}{7}[/tex]

[tex]P(Green) + P(Yellow)= \frac{4}{7}[/tex]

This is false because: [tex]\frac{4}{7} \ne \frac{1}{2}[/tex]

[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]

[tex]P(Green) + P(Yellow)= \frac{3}{8} + \frac{1}{8}[/tex]

Take LCM

[tex]P(Green) + P(Yellow)= \frac{3+1}{8}[/tex]

[tex]P(Green) + P(Yellow)= \frac{4}{8}[/tex]

[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]

This is true

[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]

[tex]P(Green) + P(Yellow)= \frac{1}{4} + \frac{1}{4}[/tex]

Take LCM

[tex]P(Green) + P(Yellow)= \frac{1+1}{4}[/tex]

[tex]P(Green) + P(Yellow)= \frac{2}{4}[/tex]

[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]

This is true

Other options are also false

The vertex would be (6,1)

Step-by-step explanation:

The vertex is the midway between the focus and the directrix. The X of the vertex would be the same but to get the Y of the vertex you would need to take the average of the Y values. (6, 4 + (-2)/2) (6,1)

Answer:

y=-9/7x-15/14

Step-by-step explanation:

Slope-intercept form is y=mx+b

The y-coordinate is on one side, and the slope, x-coordinate, and y-intercept are on the other side.

18x+14y+15=0

-15              -15

18x+14y=-15

-18x       -18x

14y=-15-18x

14y=-18x-15

÷14        ÷14

y=-9/7x-15/14

Hope this helps!

The statement is false and same mean can have different variability

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

Let the mean of the data be represented as M

Now , The mean is a measure of central tendency that represents the average value of a set of data, but it does not provide information about the variability or spread of the data.

For example, consider the following two sets of data:

Set 1: 1, 2, 3, 4, 5 (mean = 3)

Set 2: 0, 2, 3, 4, 6 (mean = 3)

Both sets have the same mean of 3, but Set 1 has a smaller range (4) compared to Set 2 (6). The range is a measure of variability that represents the difference between the maximum and minimum values in a set of data.

Hence , two sets of data with the same mean can have different variability,

Answer:

150 workers are at the company

Step-by-step explanation:

If 20% of the workers is equal to 30 workers than in order to find 100% of the worker you need to multiply the percentage with a number that makes it 100% and then multiply that number to the 30 workers so

20% * 5 = 100%

30 * 5 = 150

so 100% of the workers is equal to 150 workers

t=100-s

Step-by-step explanation:

Since we know T as the total amount, we need to figure out how much was spent from the $100 Julie has. She can't gain more money magically so you have to take away from the 100. The amount taken away is the S (a.k.a- how much was SPENT). After putting that together, you get t=100-s.

The age of the oldest sibling is 15 years old.

What is consecutive number?

Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers.

Here, let the age of youngest sibling be x years

              the age of middle sibling be (x+1) years

              the age of oldest sibling be (x+2) years

According to question,

        x + (x+1) + (x+2) = 42

          3x + 3 = 42

           3x = 39

             x = 13

Thus, the age of the oldest sibling is (x+ 2) years = 15 years old.
