It is given that m ∥ n, m∠1 = 50° , and m∠2 = 42°. By the triangle sum theorem, m∠3 = 88°. Because corresponding angles formed by two parallel lines and a transversal are congruent, ∠3 ≅ ∠4. By the angle congruence theorem, m∠3 =m∠4. Using substitution, 88°=m. Angles 4 and 5 form a linear pair, so by the linear pair postulate, m∠4 + m∠5=180°. Substituting gives 88° + m∠5=180°. Finally, by the subtraction property of equality, m∠5 = 92°.

Tim is now earning $500 per week after receiving an increase of $45 per week. What was Tim's previous weekly salary

Mars2501 [29]

Now Tim gets $500 after it $45 was added to what he had last week

That means that
"What Tim earned last week" + $45 = $500

Subtract $45 from $500
$500-$45= $455

If you're not sure check your work
If I make $455 now and next week I get $45 more next week
$455+$45=$500
Next week I make $500

Calculate the variance of the following set of data. 3, 33, 303, 233, 3, 73, 83, 63

andrew-mc [135]

Answer:

12083.929

Step-by-step explanation:

First step: find the mean of the data.

mean = 3+33+303+233+3+73+83+63

= 794

= 99.25

Second step: Now we calculate each dog's difference from the Mean.

Example : 3–99.25=96.25

Answer: (-96.25)+(-66.25)+203.75+133.75+(-96.25)+(-26.25)+(-16.25)+(36.25)

Third step: To calculate the Variance, take each difference, square it, and then average the result.

s² = (-96.25)²+(-66.25)²+203.75²+133.75²+(-96.25)²+(-26.25)²+(-16.25)²+(36.25)²

8–1

= 9264.063+4389.063+41514.063+17889.063+9264.063+689.063+264.063+1314.063

= 84587.5

= 12083.929

Variance Formula:

Variance = s² =Σ(xi− x )²

The heights of flowering cherry trees are normally distributed with a mean of 11.5 feet, and a standard deviation of 1.7 ft. fin

Fittoniya [83]

Mean (μ) = 11.5 feet

Standard deviation (σ) = 1.7 feet

First we need to find the z-score for less than 13.5 feet.

The formula of z-score is : z = (X - μ)/σ

Here X= 13.5, so z = $\frac{(13.5-11.5)}{1.7}$

z = $\frac{2}{1.7}$ = 1.18

P(X < 13.5) = P(z< 1.18) =P(z< (1.1 + .08)) = 0.8810 (from z-score table)

P(X< 13.5) = 88.1% (for making percentage from decimal, we need to multiply by 100)

So, the probability that a randomly selected tree is less than 13.5 feet tall = 88.1%
