If one woman is selected find the probability that her height is less than 65 inch with a mean of 64.4 and standard deviations of 1.8

Answers

The probability of one woman to have height less than 64.4 in is 0.6293

Explanation:

Given:

Mean, μ = 64.4

Standard deviation, δ = 1.8

Probability that the height of the woman is less than 65 inch = ?

So,

P(x < 65) = 65 - μ / δ

$=(65 - 64.4)/(1.8)\n \n= 0.33$

P (x < 65) = P( z < 0.33)

Finding the probability value from the z table we get:

P( z < 0.33) = 0.6293

Therefore, the probability of one woman to have height less than 64.4 in is 0.6293

X^2 + 20x + 28 = 9 find the graphing/vertex form

Answers

Answer: $(x+10)^2+119=0$

Step-by-step explanation:

For a quadratic equation, the vertex form is given by : $y=a(x-h)^2+k$ , where (h, k) is the vertex.

The given quadratic equation: $x^2 + 20x + 28 = 9$

Subtract 9 from both sides

$=x^2+20x+19=0$

compare this to $x^2+bx=c$ , and add $((b)/(2))^2$ both sides

b= 20

$x^2+20+100+19=-100$ [(b/2)²=20/2=10]

$\Rightarrow\ x^2+2(x)(10)+10^2+119=0$

$\Rightarrow\ (x+10)^2+119=0\ \ \ [\because\ (a+b)^2=a^2+b^2+2ab]$

So, the vertex form : $(x+10)^2+119=0$

A wide screen television display measures approximately 15 inches high and 27 inches wide. A television is advertised by giving the approximate length of the diagonal of its screen. How should the television be advertised?A) 36 in.
B) 31 in.
C) 30 in.
D) 21 in.

Answers

The answer would be 31 in.

First do the Pythagorean theorem.

225+ 729= 954

Then find the square root of 954 which is 30.88 repeating, so round up to 31 in.

The answer would be B) 31 in.
