the sitting height (from the bottom of the seat to the top of the person's head) of female drivers is normally distributed with a mean of 34 inches and a standard deviation of 1.4 inches as shown below. If a car company designs a vehicle so that the roof is 34 inches from the bottom of the seat, what percentage of women would not fit in the driver's seat? A. 40% B. 50% C. 50.1% D. 60%

Answers

Answer:

B; 50%

Step-by-step explanation:

Here, we want to calculate the percentage of women that will not fit in the driver’s seat

We proceed as follows;

We start with calculating the z-score of this;

That would be ;

(x-mean)/SD

in this case;

x = 34 inches

mean = 34 inches

SD = 1.4 inches

Thus, we have that;

(34-34)/1.4 = 0/1.4 = 0

when z-score is 0, we are at the center of the distribution

A z-score of 0 corresponds to exactly 50%

Help!! I need this ASAP

Answers

Answer:

x=15

Step-by-step explanation:

Well, you have 2 numbers that sum up to 90 (the angle) so you can first minus the one you know, making your number from 90-30=60. Now all thats left is the 4x=60, which you can do 60/4=15 to get your answer that x=15.

Answer:

x = 15

Step-by-step explanation:

The sum of 30 and 4x = 90, that is

4x + 30 = 90 ← equation to solve

Subtract 30 from both sides

4x = 60 ( divide both sides by 4 )

x = 15

Bill can mow the lawn in 2 hours, and his younger brother Tom can now it in 3 hours. If both brothers mow the lawn together, how many hours will it take them?

Answers

If they both stop at 1/2 of the lawn, it would take them 1.5 hours to finish.

You can find this by finding how long it would take bill to mow the lawn and divide that time in half, and the same with tom.

Since Tom would take longer to finish his half, it can be assumed that Bill will stop once he reaches his half

y=1−2x;x=9 can you please help

Answers

Answer:

17

Step-by-step explanation:

since you are given that x is 9 all you have to do is plug it in. So 1-2(9) 2 times 9 is 18 so 1-18=17

y = 1 - 2x
y = 1 - 2(9)
y = 1 - 18
y = -17

The answer is -17

help me solve this problem? algebra I

Answers

Answer: B

Explanation: 6x - y = 10

First we need to put this is y=Mx+b format

This gives us: -y = -6x + 10

Now we need to remove the negative from y. To do this multiply both sides of the equation by -1

This gives us y = 6x - 10

We know that -10 is the y intercept when x = 0. Now if we plug in 0 for why we get
0 = 6x - 10

Add ten to both sides (10=6x) then divide by 6 (10/6=x) or x = 5/3, y = -10

I need to solve for the angle, but I just don't know how to do it! The equation is: Cos A=Sin3A

Can someone explain the formula so I can know how to do it, I will really appreciate it!

Answer:

  A = 22.5°, 45°, 112.5°, 202.5°, 225°, 292.5°

Step-by-step explanation:

Use the angle reduction formula to reduce this to an expression involving only sine or cosine, then solve the resulting higher-degree polynomial.

   sin(3x) = 3sin(x) -4sin³(x)

Using the identity for cosine, we have the radical equation ...

  √(1 -sin²(A)) = 3sin(A) -4sin³(A)

Squaring both sides, we have ...

  1 - sin²(A) = 9sin²(A) -24 sin⁴(A) +16sin⁶(A)

Letting z = sin²(A), this is the cubic equation ...

  1 -z = 9z -24z² +16z³

  16z³ -24z² +10z -1 = 0

Solving this by the usual methods, we find its factors to be ...

  (2z -1)(8z² -8z +1) = 0

  8(2z -1)((z -1/2)² -1/8) = 0 . . . . quadratic in vertex form

Then the roots are ...

  z = (1 ±√(1/2))/2, z = 1/2

The angle solutions are ...

  A = arcsin(±√z)

Of course, these need to be adjusted to fall in the domain of interest, and checked for extraneous solutions.

For z = 1/2-√(1/8), the angles are ...

  A = ±22.5°  ⇒  22.5°, 157.5°, 202.5°, 337.5°

For z = 1/2, the angles are ...

  A = ±45°  ⇒  45°, 135°, 225°, 315°

For z = 1/2+√(1/8), the angles are ...

  A = ±67.5°  ⇒  67.5°, 112.5°, 247.5°, 292.5°

The angles that are in bold are the actual solutions; the others are extraneous.

_____

All of the above is "the hard way." A much simpler approach is to take advantage of the identity ...

  cos(a) -sin(b) = (1/2)·sin(b/2 -a/2 -π/4)·sin(b/2 +a/2 -π/4)

Then you can use the zero product rule to find (for a=A, b=3A) ...

  (3A/2 -A/2 -π/4) = nπ  ⇒  A = nπ +π/4  ⇒  45°, 225°

  (3A/2 +A/2 -π/4) = nπ  ⇒  A = (nπ +π/4)  ⇒  22.5°, 112.5°, 202.5°, 292.5°

_____

Rewriting the equation as a function equal to zero, the solutions are the x-intercepts of the graph. In the attached, the x-axis is set to degrees.

  f(A) = cos(A) -sin(3A) = 0
