Answer:

D) 0.5764.

Step-by-step explanation:

According to a standard z-score table, a z-score of -0.5 corresponds to the 0.3085-th percentile of a standard normal distribution.

Furthermore, a z-score of 1.2 corresponds to the 0.8849-th percentile of a standard normal distribution.

Therefore, the area under the standard Normal curve corresponding to -0.5 < Z < 1.2 is:

A = 0.8849-0.3085\\A=0.5764

The answer is option D) 0.5764.

A gym membership at one gym costs $10 every month plus a one-time membership fee of $15, and a gym membership at another gym cos
Minchanka [31]

Answer: Let us assume that the number of months after which

the gym memberships will cost the same = x

Then

15 + 10x = 40 + 4x

10x - 4x = 40 - 15

6x = 25

x = 25/6

 = 4 1/6

So the membership fee of both the gyms will become same after 4 1/6 months. You can also consider that as after 5 months the membership fees of both the gyms will become same. I hope the procedure is not very complicated for you to understand.

Step-by-step explanation: Hope this helps!!

The work of a student to solve a set of equations is shown:
Ivahew [28]
Step 1. Equation B could not have simplified out to 3y= 3 - 4z because Equation A's original equation was y= 15 - 2z. That means after the multiplication by -3, -3(y)= -3(15 - 2z) it would equal -3y= -45 + 6z.

Consider the line 2x-7y=-7. Find the equation of the line that is perpendicular to this line and passes through the point (-8,-6
monitta

Step-by-step explanation:

2x - 7y = -7

2x + 7 = 7y

y = (2/7)x + 1

the slope of the line is the factor of x : 2/7

FYI that is the ratio y/x and means, when x changes by 7 points to the plus (right) side, then y changes 2 points to the plus (up) side.

the parallel line will have the same slope, of course. just a different y-axis-interception point. that means, the "+" term at the end changes. changes to what ?

well, we use the given point coordinates

-6 = (2/7)×-8 + c

-6 = -16/7 + c

-42/7 = -16/7 + c

-26/7 = c

so, the equation of the parallel line is

y = (2/7)x - 26/7

y = (2/7)×(x - 13)

the perpendicular line is a line that intercepts our original line with a 90 degree angle.

that means its slope will switch x and y of the original line slope and also flips the sign (from + to - or vice versa).

=> the slope of the perpendicular line is -7/2.

the line equation looks like

y = (-7/2)x + c

and again, we use the given point coordinates to find the missing c (y-intercept).

-6 = (-7/2)×-8 + c

-6 = -7×-4 +c

-6 = 28 + c

-34 = c

so, the full equation of the perpendicular line is

y = (-7/2)x - 34
