If m∠CGB = 101 , then what is m∠DGA

m<DGA = 101

Step-by-step explanation:

Angle 1 and angle 3 are vertical angles. Vertical angles are 2 angles that are across from each other and share a vertex. All vertical angles are congruent. Congruent means that the angles have the same measurement. Therefore, since angle 1 is 101 degrees, angle 3 must be the same.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
