Answer:

55%

If 1,210 people would buy that type of car again, they were satisfied with it.

The fraction of people who were satisfied would be \frac{1210}{2200}.

To find a percentage, we need to divide the top of the fraction by the bottom, then multiply by 100.

1210/2200 is equal to 0.55. This is the decimal form of the fraction, but we need the percentage.

0.55 x 100 is equal to 55.

The answer is 55%

40. What is the value of x?<br> (7x – 8)°<br> (6x +11°)<br> Drawing not to scale
fenix001 [56]

<u>Answer:</u>

  • <u>The value of x is 19.</u>

<u>Step-by-step explanation:</u>

<u>We know that both of these expressions are equal because of vertically opposite angles. Let's solve.</u>

  • => 7x - 8 = 6x + 11
  • => 7x - 6x = 19
  • => x = 19

<u>Hence, the value of x is 19.</u>

Hoped this helped.

Suppose that the number of gallons of milk sold per day at a local supermarket are normally distributed with mean and standard d
miv72 [106K]

Answer:

<em>The probability that on a given day the supermarket will sell between 304 and 305 gallons of milk is 0.0127 or 1.27%</em>

Step-by-step explanation:

<u>Normal Distribution</u>

The graph of the Normal Distribution is also called the Bell Curve because of its particular shape. It occurs naturally in many real situations where a random variable needs to be modeled according to experimental results.

To evaluate the probability of a Normal Distribution, we need some kind of digital means because the formula cannot be computed directly in a formula. We'll use the MS Excel's specialized formula NORMDIST for the first value of x=304:

NORMDIST( 304 , 319.9 , 26.4 , true ) = 0.2735

Now for x=305:

NORMDIST( 305 , 319.9 , 26.4 , true ) = 0.2862

Both values are now subtracted to get the required probability

P(304

The probability that on a given day the supermarket will sell between 304 and 305 gallons of milk is 0.0127 or 1.27%

In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of third angle os 88 degrees
Volgvan

Answer:

Answers: 46, 23, and 111

Step-by-step explanation:

To answer, we need to know the angles. Therefore, give each angle a name. Angle 1 will be x, 2 will be y, 3 will be z. So, using this system of equations:

x=2y

z=y+88

x+y+z=180

Substituting, z = 1/2(x)+88, now plug z into the third equation:

x+1/2(x)+1/2(x)+88=180

this simplifies to 2x+88=180

subtracting 88 from both sides leaves 2x=92

x=46

plug this in to the first equation: 46 = 2y, so y = 23

plug this into the third one leaves z = 111

Hope this helps!

deff fn [24]

Answer: masses are 825 g and 1125 g

Step-by-step explanation: masses of hamsters are x and x+ 300 g.

Total mass is x+(x+300) = 1950

2x = 1650 g and x= 825
