Umnica [9.8K]3 years ago

Answer:

see explanation

Step-by-step explanation:

Since XY bisects ∠ WXZ then ∠ WXY = ∠ YXZ , thus

7x - 7 = 5x + 3 ( subtract 5x from both sides )

2x - 7 = 3 ( add 7 to both sides )

2x = 10 ( divide both sides by 2 )

x = 5

(b)

∠ WXY = 7x - 7 = 7(5) - 7 = 35 - 7 = 28°

(c)

∠ YXZ = 5x + 3 = 5(5) + 3 = 25 + 3 = 28°

(d)

∠ WXZ = ∠ WXY + ∠ YXZ = 28° + 28° = 56°

An expression is defined as a set of numbers, variables, and mathematical operations. The simplified version of the given expression is (3√2-2)√x³.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given expression \sqrt{32x^3} - \sqrt{16x^3} + \sqrt{4x^3} -\sqrt{2x^3} can be simplified as shown below.

\sqrt{32x^3} - \sqrt{16x^3} + \sqrt{4x^3} -\sqrt{2x^3}\\\\=\sqrt{x^3}(\sqrt{32}-\sqrt{16}+\sqrt{4}-\sqrt{2}})\\\\= \sqrt{x^3} (4\sqrt{2}-4+2-\sqrt2)\\\\= \sqrt{x^3} (3\sqrt{2}-2)

Hence, The simplified version of the given expression is (3√2-2)√x³.

What value has a z-score of -0.67, if the mean is 18 and the standard deviation is 1.68?
uranmaximum [27]
The data point is 1.6 standard deviations above the mean.
Step-by-step explanation:
Z-score
It is the number of standard deviations from the mean that a data point is. It's a measure of how many standard deviations below or above the population mean a raw score is.
A Z-score is also known as a standard score and it can be placed on a normal distribution curve.
As in this case the Z-score is +1.6, so it means the data point is 1.6 standard deviations above the mean. Hope this helps I am kinda knew to this so I hope I helped you

Our work: -2x + 4 = 5 - 3x
Vikentia [17]

Answer:

x=1

Step-by-step explanation:

-2x + 4 = 5 - 3x

Add 3x to each side

-2x+3x + 4 = 5 - 3x+3x

x +4 =5

Subtract 4 from each side

x+4-4 =5-4

x =1
