Answer:

C) When an altitude is drawn from the right angle of a right triangle it creates three similar triangles.

Step-by-step explanation:

The Inscribed Similar Triangles Theorem states that if an altitude is drawn from the right angle of any right triangle, then the two triangles formed are similar to the original triangle and all three triangles are similar to each other.

Use this data in the problem below. Follow the steps carefully. Round to the nearest tenth. Lot 1: Week 1: 600 Week 2: 300 Week

Dafna11 [192]

Answer:

Step-by-step explanation:

The given data set is:

Week 1: 600

Week 2: 300

Week 3: 500

Week 4: 900

The following are the steps to find the standard deviation:

Step 1. Jim enters the data and calculates the average or mean.

$Mean=\frac{600+300+500+900}{4}=\frac{2300}{4}=575$

Step 2. Jim calculates the deviation from the mean by subtracting the mean from each value.

Data value (x) $x-{\overline{x}}$

600 25

300 -275

500 -75

900 325

Step 3. Jim squares each deviation to remove negative signs.

Data value (x) $(x-{\overline{x}})^2$

600 625

300 75625

500 5625

900 105625

Step 4. Jim sums the squares of each deviation and divides by the count for the variance.

$Variance=\frac{625+75625+5625+105625}{4}=46875$

Step 5.Jim takes the square root of the variance to find the standard deviation.

$Standard deviation=\sqrt{46875}=216.50$

Help with this math question please

gtnhenbr [62]

The answer is B x = -4. x= 3

You must factor the equation by find what 2 numbers can multiply to equal -12 and add to equal 1.

-3 and 4 are the two numbers. Now to put it in factor form would be:

(x - 3)(x + 4) = 0

They y also must equal zero.

Since its equals to 0, we must solve for x for the binomial.

x - 3 = 0 ; x = 3

x + 4 = 0 ; x = -4

The answer you get from solving x, is that answer
