Height of Sandra that is already mentioned in the question is = 4 feet
Percentage by which Pablo is taller than Sandra = 10%
Height by which Pablo is greater than Sandra = (10/100) * 4
   = (4/10)
   = 0.4 feet
Then height of Pablo is = 4 + 0.4
   = 4.4 feet
Now we can find the height of Michaela as she is 8% taller than Pablo.
Percent by which Michaela is taller than Pablo = 8%
Height by which Michaela is greater than Pablo = (8/100) * 4.4
      = (2 * 4.4)/25
      = 0.35 feet
Then the height of Michaela = (4.4 + 0.35) feet
   = 4.75 feet
So height of Michaela is 4.75 feet. This is the way this problem has to be solved.

If you would like to know how tall is Michaela, you can calculate this using the following steps:

Sandra ... s = 4 feet tall
Pablo ... p = 10% taller than Sandra: 110% * s = 110% * 4 = 110/100 * 4 = 4.4 feet tall
Michaela ... m = 8% taller than Pablo: 108% * p = 108% * 4.4 = 108/100 * 4.4 = 4.752 feet tall

Result: Michaela is 4.752 feet tall.

Answer: B. H(t) = -6.9(t - 2.3)² + 112

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

The vertex form of a quadratic equation is: y = a(x - h)² + k

where (h, k) is the vertex ⇒ k is the maximum height

the distance traveled is when y = 0 ⇒ $x=\sqrt{\dfrac{-k}{a}}+h$

Given: H(t) = -7.1(t - 2.3)² + 98

maximum height (k) = 98 feet

distance traveled (x) = $\sqrt{\dfrac{-98}{-7.1}}+2.3$ = 6.02 seconds

A) H(t) = -7.5(t - 2.2)² + 112

maximum height (k) = 112 feet

distance traveled (x) = $\sqrt{\dfrac{-112}{-7.5}}+2.2$ = 6.06 seconds

B) H(t) = -6.9(t - 2.3)² + 112

maximum height (k) = 112 feet

distance traveled (x) = $\sqrt{\dfrac{-112}{-6.9}}+2.3$ = 6.33 seconds

C) H(t) = -6.9(t - 2.4)² + 95

maximum height (k) = 95 feet

This has a lower height than the given equation.

D) H(t) = -7.5(t - 2.3)² + 95

maximum height (k) = 95 feet

This has a lower height than the given equation.

Both options A and B travel higher and stay in the air longer than last year's winner, however option B stays in the air longer than option A.

Suppose taxi fare from Logan Airport to downtown Boston is known to be normally distributed with a standard deviation of $2.50.

Mariulka [41]

Answer:

95% Confidence interval for taxi fare: ($20.5,$24.2)

Step-by-step explanation:

We are given the following data set: for fares:

$22.10, $23.25, $21.35, $24.50, $21.90, $20.75, and $22.65

Formula:

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{156.5}{7} = 22.35$

95% Confidence interval:

$\bar{x} \pm z_{critical}\frac{\sigma}{\sqrt{n}}$

Putting the values, we get,

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

$22.35 \pm 1.96(\frac{2.5}{\sqrt{7}} ) = 22.35 \pm 1.85 = (20.5,24.2)$

Solve the system by graphing. It is REQUIRED to check your solution. Show work for this problem on your work page.

Hunter-Best [27]

Answer:

y=x-1

y=-2x-4

although I cant summon a graph for this one, I can give cords

for first graph (-2,-3),(-1,-2),(0,-1), (1,0),(2,1)

For second graph the slope is down 2 over 1, and begins at (0,-4).

(-2,0)(-1,-2),(0,-4),(1,-6),(2,-8)
