Answer: 22.5°

Each of the two smallest angles in the triangle are 22.5°

Step-by-step explanation:

Isosceles triangle is a triangle with two equal sides and two equal angles

The largest angle is 50% more than right angle

Let L represent the largest angle

L = 150% of 90°

L = 1.5 × 90°

L = 135°

The other two angles are equal and can be represented by x

Sum of angles in a triangle is 180°

L + x + x = 180°

2x = 180 - L

x = (180 - 135)/2

x = 45/2

x = 22.5°

Two integers a and b have a product of 24.what is the least possible sum of a and b
OverLord2011 [107]
A x b = 24

Possible values of a and b are:
1 x 24 = 24
2 x 12 = 24
3 x 8 =24
4 x 6 = 24

The possible sums of a and b are:
1 + 24 = 25
2 + 12 = 14
3 + 8 = 11
4 + 6 = 10

Therefore, the least possible sum of a and b is 10.

9966 [12]

Answer:

x = -20

Step-by-step explanation:

2(x+7) 2x + 20  - 2 =  x+4  2x + 8

2x+14 + 2x + 20 - 2 = x + 4 + 2x + 8

4x +32 = 3x + 12

x = -20

A researcher is using a two-tailed hypothesis test with α = .05 to evaluate the effect of a treatment. If the boundaries for the
Solnce55 [7]

Answer:

A. ​n = 22

Step-by-step explanation:

Hello!

The researcher conducted a one-sample t-tas with the following hypotheses:

H₀: μ = μ₀

H₁: μ ≠ μ₀

α:0.05

The one-sample t-test has "n-1" degrees of freedom and since the hypotheses are two-tailed you know that the rejection region will be divided into two tails with "α/2" for each tail.  ± t_{n-1;1-\alpha /2}

If α:0.05 then α/2:0.025 and 1-α/2= 0.975

Using the given sample sizes as a reference you look in the table for the corresponding DF for an accumulated probability of 0.975

For n = 22 t_{21;0.975}= 2.080

For n= 21  t_{20;0.975}= 2.086

For n= 20 t_{19;0.975}= 2.093

The correct answer is a) n= 22

I hope this helps!
