4 0

Answer:

12 or 4

Step-by-step explanation:

h square -h(12+4)+48

h square-12h-4h+48=0

h(h-12)-4(h-4)=0

h-12=0 equation 1

h-4=0 equation 2

from eqn 1

h-12=0

h=12

from eqn 2

h-4=0

h=4

Therefore value of h=12,4

Aaron tracks the time it takes him to mow lawns by writing coordinate points relating x, the time in hours it takes to mow a law
Alika [10]

Answer:

2 acres/hour

Step-by-step explanation:

Please share the possible answer choices.  Thank you.

If two points on this straight line graph are (3, 1.5) and (5, 2.5), then we can find the slope of this line as follows:

As we move right from x = 3 to x = 5, x (the "run") increases by 2 and y (the "rise") increases by 1.  Thus, the slope of this line is m = rise / run = 2/1, or

m = 2.

                                                                    area mowed

The units of measurement here are m = ----------------------

                                                                     time spent

and so we could conclude that the rate is 2 acres per hour.

The perimeter of a rectangular garden is 364 feet. If the length of the garden is 99 feet, what is its width?
gregori [183]
P=2(L+W)
P=364
L=99
sub and find W
364=2(99+W)
divide both sides by 2
182=99+w
subtract 99 from both sides
83=W

w=83ft

What actions did colonists take to protest the Townshend Acts?
brilliants [131]

Answer:

The Townshend Acts would use the revenue raised by the duties to pay the salaries of colonial governors and judges, ensuring the loyalty of America's governmental officials to the British Crown. However, these policies prompted colonists to take action by boycotting British goods.

Determine the two z-scores that separate the middle 87.4% of the distribution from the area in the tails of the standard normal
marusya05 [52]

The two z-scores are -1.53 and 1.53

Step-by-step explanation:

To find the two z-scores that separate the middle 87.4% of the distribution from the area in the tails of the standard normal distribution

  1. Assume that z-score is between -c and c ⇒ P(-c < z < c) = the given value
  2. Find the value of P(z < -c or z > c) = 1 - the given value
  3. P(z < -c) + P(z > c) = the answer of the previous step
  4. 2*P(z < -c) = the answer of the previous step
  5. Find the value of P(z < -c)
  6. In the z-table having area to the left of z, look for the value closest to the value of P(z < -c) inside the table to find the closest value of z

∵ P(-c < z < c) = 87.4%

∵ 87.4% = 87.4 ÷ 100 = 0.874

∴ P(-c < z < c) = 0.874

∵ P(z > c) = 1 - 0.874 = 0.126

∴ P(z < -c) + P(z > c) = 0.126

∵ P(z > c) = P(z < -c)

∴ P(z < -c) + P(z < -c) = 0.126

∴ 2*P(z < -c) = 0.126

- Divide both sides by 2

∴ P(z < -c) = 0.063

Let us use the z-table to find the corresponding values of

z to 0.063

∵ The corresponding value of z to 0.063 = -1.53

∴ The two z-scores = -1.53 and 1.53

The attached figure for more understand

The two z-scores are -1.53 and 1.53
