Answer:

x=57

Step-by-step explanation:

x+28+x+38=180

Step 1: Simplify both sides of the equation.

x+28+x+38=180

(x+x)+(28+38)=180(Combine Like Terms)

2x+66=180

2x+66=180

Step 2: Subtract 66 from both sides.

2x+66−66=180−66

2x=114

Step 3: Divide both sides by 2.

2x/2=114/2

Answer:

x=57

Answer:

57

Step-by-step explanation:

x+28+x+38=180

2x+66=180

Answer:

y=-1x-6

Step-by-step explanation:

the slope is -1

use y=mx+b

Plug  the point into y=mx+b, -7=-1(1)+b

-7=-1+b

add 1 both sides the y- intercept is b=-6

Answer:

2.01030927835 or $2.01

Step-by-step explanation:

16 ft 2 in = 194 in

390/194 = 2.01030927835

Simplify, $2.01

Hope this Helps :)

Answer:

A. x>-12

Step-by-step explanation:

-2x/3+7<15  Subtract 7 on both sides.

         -7  -7

-2x/3<8       -2x/3 is equal to -2/3x, so you can simplify to that.

-2/3x<8       Because you have to isolate x, multiply by the reciprocal of the          

*-3/2  *-3/2  fraction. This will divide by -2/3 on both sides.

x>-12            Remember, because you multiplied by a negative, you have to flip the inequality sign.

Hope this helps you! Have a nice day c:

Answer:8

Step-by-step explanation:

Answer:

The 16 percent of the goldfish are smaller from 1.25 inches.

Step-by-step explanation:

Let X denote the size of a particular goldfish.

It is provided that the mean size is, μ = 1.5 inches and standard deviation of the size is, σ = 0.25 inches.

Assume that X is normally distributed.

Compute the size of a goldfish such that only 16 percent of the goldfish are smaller from such size as follows:

P (X < x) = 0.16

⇒ P (Z < z) = 0.16

The z-value for such a probability is:

z = -0.99

*Use a z-table.

Compute the value of x as follows:

[tex]z=\frac{x-\mu}{\sigma}\\\\-0.99=\frac{x-1.5}{0.25}\\\\x=1.5-(0.99\times 0.25)\\\\x=1.2525\\\\x\approx 1.25[/tex]

Thus, the 16 percent of the goldfish are smaller from 1.25 inches.

Answer:

D. y=4x-1

Step-by-step explanation:

y=mx+b (This is the slope intercept formula) The M(X) represents the slope and the B represents the y intercept.

y=4x-1

Answer:

d. y = 4x -1

Step-by-step explanation:

y = mx + b

  m= 4

  b= -1

y = (4)x + (-1)

y = 4x - 1

can i get brainliest please?

Answer:

150

Step-by-step explanation:

Using 8 rows leaves  2 positions unoccupied implies that the population of the number  of members in the band is 2 less than a  multiple of 8. That makes this an even  number.

Similarly, we understand that the number  of members is 3 less than a multiple of  9. So, If we list the even numbers  that are 3 less than multiples of 9  between 100 and 200 and are even; we have:

117 – 3, 135 – 3, 153 – 3, 171 – 3,  189 – 3

= 114, 132, 150, 168, 186  

Also, the numbers that are two less than  a multiple of 8:  

102, 110, 118, 126, 134, 142, 150, 158,  166, 174, 182, 190, 198

From above, we will realize that the number common in both is 150

Let's check if that satisfy our calculation;

SO:

150/8 = 18 remainder 6 ; Thus 8 - 6 = 2 (positions)

150/9 =  16 reminder 6 ;  Thus  9 - 6 = 3 (positions)

Hence the number of members in the band if the membership is between 100 and 200 is 150

Answer:

7 because u are changing division to mutiplication its called replicate

Answer:

since 2 and 1/3 is a mixed number change it into an improper fraction so it will be 7/3 / 1/3 find the reciprocal of the second fraction that is one of the three the reciprocal will be 3/1 so it will be 7/3 * 3/1 because when you find the reciprocal of a second fraction you also find the reciprocal of the sine and in this case division will change to multiplication when you multiply it you'll get the answer to be 7 hope it helps

Step-by-step explanation: What you know is for every 8 girls that is 1/3 of the total number of girls, so you just multiply 6 time 3. Hope this helped :)

Answer:

The second option

Step-by-step explanation:

The domain is the x values and the range is the y values

Answer:

48

Step-by-step explanation:

The significance level is 95%

Z-alpha/2 = 1.96 at 0.05 from the standard normal distribution table.

The standard deviation has been given to be 7

Margin of error is 2

We solve further using the formula:

n = (z-alpha/2 * sd/ME)²

n = (1.96 * 7/2)²

n = (1.96x3.5)²

= 6.86²

= 47.0596

This is approximately

n = 48

So the sample size they should be selected should be 48 for at 95% confidence level.
