Answer: YES
<u>Step-by-step explanation:</u>
8p - 2q = 14
8(1) - 2(-3) = 14
8 - -6 = 14
8 + 6 = 14
14 = 14
TRUE
Answer:
any score that lies between 88.8 and 97.2 is within one std. dev. of the mean
Step-by-step explanation:
One std. dev. above the mean would be 93 + 4.2, or 97.2. One std. dev. below the mean would be 93 - 4.2, or 88.8.
So: any score that lies between 88.8 and 97.2 is within one std. dev. of the mean.
Answer:
1. <B, <A, <C
2. <E, <D, <F
Step-by-step explanation:
Recall: the longest side of a triangle would be opposite the largest angle, while the shortest side of a triangle would be opposite the smallest angle.
1. <B is opposite the shortest side, 3 (smallest angle)
<A is opposite the medium side, 4 (medium angle)
<C is opposite to the largest side, 5 (largest angle)
Therefore, the angles in ascending order would be:
<B, <A, <C
2. <E is opposite the shortest side, 5 (smallest angle)
<D is opposite the medium side, 6 (medium angle)
<F is opposite to the largest side, 7 (largest angle)
Therefore, the angles in ascending order would be:
<E, <D, <F
Answer:
Step-by-step explanation:
Angle A = 90°
Angle B = 45°
According to the angle sum property
Angle A + Angle B + Angle C = 180°
90° + 45° + Angle C = 180°
Angle C = 45°
As the two angles are equal so the triangle is right angle isosceles triangle.
Answer:
x = - 8
Step-by-step explanation:
4x - 9 + 3x = 8x - 1
7x - 9 = 8x - 1
7x - 8x - 9 = 8x - 8x - 1
- x - 9 = - 1
- x - 9 + 9 = - 1 + 9
- x = 8
- x ÷ - 1 = 8 ÷ - 1
x = - 8
