Answer:

100, -20 times time -5 makes the negatives turn it positive

Answer:

22.5

Step-by-step explanation:

The required Distribution, selection and probability is X to U(4,11), x to N (7.5, 0.3415) and 0.87932 respectively.  

(a) Distribution of X is uniform distribution  X to U(4,11).

(b) Sample size (n) = 35, distribution of mean would be moderate with value = (4+11)/2 = 7.5

Standard deviation = √ [(11-4)^2/(12*35] = 0.3415
Now
x to N (7.5, 0.3415)

(c) We have to find probability that the average of 35 numbers will be less than 7.9.

P(x < 7.9) = P(x < 7.9; 7.5; 0.3415)
Z = (7.9 -7.5)/0.3415
Z = 1.1713
P(x< 7.9)= P(Z < 1.1713)= 0.87932.

Thus, The required Distribution, selection and probability is X to U(4,11), x to N (7.5, 0.3415) and 0.87932 respectively.

Step-by-step explanation:

Answer:

x=22

Step-by-step explanation:

We would do the opposite so "six less" we would add 6 to 38. 6+38= 44 and "twice a number" we would divide by 2. 44 /2= 22. So the answer would be 22.

Hope this helps! :)

Answer:

Answer is 22

Step-by-step explanation:

38+6=44

44 ÷ 2= 22

trust me i just got it

Answer:

3/8g + 2 = 5  

Subtract the number 2 from both sides of the equation.

3/8g = 3

Now divide 3/8 from both sides of the equation.

3/8 divided by 3/8 equals 0.  3 divided by 3/8 equals 8.

The final answer is:

g = 8

------------------------------------------------------------------------------------------

Check your answer:

3/8g + 2 = 5

Substitute 8 into the spot where the variable g was.

3/8 X 8 + 2 = 5

So our answer x = 8 is true.

Hello! The l l  notation indicates "absolute value"

Keep in mind that the absolute value is always positive. The absolute value is the distance from zero. The distance is never negative.

So

Answer:

C The car accelerated for 6 seconds and continued at a constant speed

Answer:

answer to the equation is

[tex]y = 2x + 11[/tex]

Step-by-step explanation:

[tex]y = mx + b[/tex]

first find the slope of the line using the two points

[tex]slope \: m = \frac{y2 - y1}{x2 - x1} = \frac{23 - 5}{6 - ( - 3)} \\ = \frac{18}{9} \\ slope \: m = 2[/tex]

substitute 2 for m and use one of the points for x and y and solve for b

[tex]5 = 2( - 3) + b \\ 5 = - 6 + b \\ 5 + 6 = b \\ b = 11[/tex]

Now that you found b, the y-intercept, you can substitute that into the equation for your line

[tex]y = 2x + 11[/tex]

Answer:

50°, 60°, 70°

Step-by-step explanation:

Sum the parts of the ratio, 5 + 6 + 7 = 18 parts

The 3 angles in a triangle sum to 180° , then

180° ÷ 18 = 10° ← value of 1 part of the ratio, then

5 parts = 5 × 10° = 50°

6 parts = 6 × 10° = 60°

7 parts = 7 × 10° = 70°

The angle measures of the triangle are 50° , 60° , 70°

Answer:

$55*($7s)

Step-by-step explanation:

So there is a one time fee for the bus. Its $55. You only pay for it once. However each student has to pay $7 to get on the bus. So 7 times how ever many students there are plus 55 dollars for the bus rent fee.

Answer:

100 marks have been obtained in the hindi subject.

Step-by-step explanation:

First you have to find how many marks are obtained by one degree. So you have:

450marks/360°=1.25marks/degree

Then you have to find how many marks are obtained for each subject.

1.25marks/degree×80°= 100 marks

1.25×72= 90 marks

1.25×70= 87.5 marks

1.25×90= 112.5 marks

1.25×48= 60 marks

100+90+87.5+112.5+60=450 marks

7/8 is bigger than 6/8

Considering that angles A and C are equal, and the sum of the internal angles of a triangle is 180º, we have that:

The measure of angle A is of: 48º.

The measure of angle B is of: 84º.

The measure of angle C is of: 48º.

-----------------------------

[tex]6(x - 3) = 4(x + 1)[/tex]

[tex]6x - 18 = 4x + 4[/tex]

[tex]2x = 22[/tex]

[tex]x = \frac{22}{2}[/tex]

[tex]x = 11[/tex]

[tex]6(11 - 3) = 6(8) = 48[/tex]

The measure of angle A is of: 48º.

The measure of angle C is of: 48º.

The sum of the internal angles of a triangle is of 180º, and this is used to find the measure of angle B.

[tex]mA + mB + mC = 180[/tex]

[tex]2(48) + mB = 180[/tex]

[tex]mB = 84[/tex]

The measure of angle B is of: 84º.
