PLS HELP ITS DUE IN LIKE 20 MINS I REALLY NEED HELP WITH IT

Please help I don't understand y= 4(22-4) ÷ 3(6)+6

xxMikexx [17]

The answers is

y = 150

y-(4*(22-4)/3*(6)+6)=0

Step 1 :

Simplify $\frac{6}{1}$

Step Two:

y - 150 = 0

Michael is using a drawing program to complete a construction. Which construction is he completing? A circle is drawn with two p

Cloud [144]

Answer: A square inscribed in a circle.


Justification:

Note that by making two perpendicular lines that intersect each other in the center of the circle, he obtains 4 equidistant points on the circumference.

So, joining each pair of neighbouring points, the image will reveal 4 congruent sides joining at right angles (90°). This is the image of a square with the four vertices on the circumference.

Solve the empty gas tank of a truck needs to be completely filled. the tank is shaped like a cylinder that is 3.5 ft long with a

Dmitrij [34]

5.3 minutes.
First, let's calculate the volume of the tank. That will be the area of the base multiplied by it's length. And since it's base is a circle, the area is pi*r^2. So:
V = l*pi*r^2
V = 3.5 * pi * (2.2/2)^2
V = 3.5 * pi * (1.1)^2
V = 3.5 * pi * 1.21
V = 4.235 * pi
V = 13.30464489

So the tank has a volume of about 13.3 ft^3. Now simply divide that volume
by the rate of incoming fluid. So
13.3 / 2.5 = 5.32
Rounding to 2 significant figures gives a time of 5.3 minutes.

Tall Club International has a requirement that women must be at least 70 inches tall. Given that women have normally distributed

Marizza181 [45]

Answer:

0.0150 = 1.50% of women satisfy that height requirement.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 63.7, \sigma = 2.9$
