Answer:

Value of x is 90°

Step-by-step explanation:

Why?Imagine it as a shape of circle.

Circle has a measurement total of 360°

Semi cirlcle(half of the circle) is equivalent to 180

Now,

The bottom semi circle has a 146°

The top has a 56°

You can simply compute it by subtracting them.

$146 - 56 = 90$

Which event would be closest to having a probability

balu736 [363]

Answer: c) choosing a consonant from the set {b, c, d, e, f}

Step-by-step explanation:

Since all of the choice sets have 5 values each, a 0.8 chance = 80% = $\frac{4}{5}$ .

So find the set with 4 values that meet the criteria.

A: 5/5 = 1 = 100%

B: 1/5 = 0.2 = 20%

C: 4/5 = 0.8 = 80%

D: 0/5 = 0 = 0%

Find a counterexample to show that the statement is false. Assume all sets are subsets of a universal set U = {1, 2, 3, 4, 5}. (

natka813 [3]

Answer:

For subsets A={1,2},B={2,3},C={1,2 5} of U = {1, 2, 3, 4, 5}.

A ∪ (B − C) = (A ∪ B) − (A ∪ C) does not hold.

Step-By-Step Explanation:

U = {1, 2, 3, 4, 5}.

A={1,2}

B={2,3}

C={1,2 5}

For the Left Hand Side

B-C={3}

A ∪ (B − C)= {1,2} ∪ {3} ={1,2,3}

Likewise, the Right Hand Side:

(A ∪ B)={1,2,3}

(A ∪ C)={1,2,5}

(A ∪ B)- (A ∪ C)= {1,2,3}-{1,2,5}={3}

Since, {1,2,3} ≠ {3}, A ∪ (B − C) = (A ∪ B) − (A ∪ C) does not hold.

What point divides the line segment between (10,-2) and (-6,6) into a ratio of 5:3

olganol [36]

Answer: (0,3)

Step-by-step explanation:

You follow the formulas to find the x and y of the dividing points.

Xp= x1+ a/a+b (x2-x1)

Xp= 10+5/5+3(-6-10)

Xp=10+5/8(-16)

Solve the problem above and you end up with “0” as your x.

Yp= y1+ a/a+b (y2-y1)

Yp= -2+ 5/8 (6+2)

Yp= -2+ 5/8 (8)

Solve this problem above and you end up with “3” as your y. Therefore, the point that divides the line segment between (10, -2) and (-6,6) into a ratio of 5:3 is (0, 3).

Binomial (x - 6) and trinomial (-2x2 + x + 9) are the factors of which of the

djyliett [7]

Answer:

Option (3)

Step-by-step explanation:

If binomial (x - 6) and trinomial (-2x² + x + 9) are the factors of a polynomial then their multiplication will be equal to the polynomial.

(x - 6)(-2x² + x + 9) = x(-2x² + x + 9) - 6(-2x² + x + 9)

= -2x³ + x² + 9x + 12x² - 6x - 54

= -2x³ + 13x² + 3x - 54

Therefore, Option (3) will be the correct option.
