Find the midpoint of the segment with endpoints of (1,-6) and (-3, 4) and
Zielflug [23.3K]

Answer:

Mid point = (–1 , –1)

Step-by-step explanation:

From the question given above, the following data were obtained:

(1, –6)

(–3, 4)

x₁ = 1

x₂ = –3

y₁ = –6

y₂ = 4

Mid point = (X, Y)

X = (x₁ + x₂)/2

X = (1 + –3)/2

X = (1 – 3)/2

X = –2/2

X = –1

Y = (y₁ + y₂)/2

Y = (–6 + 4)/2

Y = –2/2

Y = –1

Mid point = (X, Y)

Mid point = (–1 , –1)

Assume the heights in a female population are normally distributed with mean 65.7 inches and standard deviation 3.2 inches. Then
maria [59]

Answer:

Choice a. approximately 0.62.

Step-by-step explanation:

This explanation shows how to solve this problem using a typical z-score table. Consider a normal distribution with mean \mu and variance \sigma^2. The z\!-score for a measurement of value x would be (x - \mu) / \sigma.

Convert all heights to inches:

  • 5\; \rm ft = 5 \times 12 \; in = 60\; \rm in.
  • 5\; \rm ft + 7\; \rm in = 5 \times 12 \; in + 7\; \rm in = 67\; \rm in.

Let X represent the height (in inches) of a female from this population. By the assumptions in this question: X \sim \mathrm{N}(65.7,\, 3.2). The question is asking for the probability P(60 \le X \le 67). Calculate the z score for the two boundary values:

  • For the lower bound, 60\; \rm in: \displaystyle z = \frac{60 - 65.7}{3.2} \approx -1.78.
  • For the upper bound, 67\; \rm in: \displaystyle z = \frac{67 - 65.7}{3.2} \approx 0.41.

Look up the corresponding probabilities on a typical z-score table.

For the z-score of the upper bound, the corresponding probability is approximately 0.6591. In other words:

P(x \le 67) \approx 0.6591

On the other hand, some z-score table might not include the probability for negative z\! scores. That missing part can be found using the symmetry of the normal distribution PDF.

The probability corresponding to P(z < 1.78) (that's the opposite of the z\!-score at the lower bound) is approximately 0.9625. By the symmetry of the normal PDF:

P(z < -1.78) = 1 - P(z < 0 - (-1.78)) \approx 1 - 0.9625 = 0.0375.

Therefore:

P(X < 60) \approx 0.0375.

Calculate the probability of the interval between the two bounds:

\begin{aligned}P(60 \le X \le 65.7) &= P(X \le 65.7) - P(X \le 60)\\ &\approx 0.6591 - 0.0375 \approx 0.62 \end{aligned}.

A merchant blends tea that sells for $3.25 an ounce with tea that sells for $2.50 an ounce to produce 90 oz of a mixture that se
Nookie1986 [14]

Answer: The amount of tea ounces that sells for $ 3.25 is 36, and the amount of tea ounces that sells for $ 2.50 is 54.

Step-by-step explanation:

We start by defining variables from the data provided:

a = amount of ounces of tea that sells for ​​$ 3.25

b = amount of ounces of tea that sells for ​​$ 2.50

c = amount of ounces of tea that sells for ​​$ 2.80

From the problem we know that a + b = c, and that 3.25 * a + 2.50 * b = 2.80 * c. You can propose a system of equations:

\left \{ {{a + b = c} \atop {3.25 * a + 2.50 * b = 2.80 * c}} \right.

Having the fact that c = 90, we can simplify the system:

\left \{ {{a + b = 90} \atop {3.25 * a + 2.50 * b = 252}} \right.

Clearing a in the first equation we get:

a = 90 - b

And substituting in the second equation we arrive at:

3.95 * (90 - b) * 2.50 * b = 252, we\ apply\ the\ distributive\ property\\ 292.5 - 3.25 * b + 2.50 * b = 252, add\ the\ terms\ containing\ b\\292.5 - 0.75 * b = 252, we\ subtract\ 292.5\ from\ both\ sides\\- 0.75 * b = -40.5, we\ divide\ by -0.75\\b = 54

Now we can use b in the first equation to get a:

a = 90 - b = 90 - 54 = 36

We verify that 36 + 54 = 90, and that 3.25 * 36 + 2.50 * 54 = 252.
