Answer: A and D
Step-by-step explanation:
Table B : not a function the value of x=3 has two images
Table C: not a function the value of x=1 has two images
Tables A and D are functions
7,440 I believe, all you need to use is basic subtraction for this.
Answer:
the sample proportion is higher
Step-by-step explanation:
What we must do is calculate the proportion of the population, we are left with the fact that out of 38 students 58% have cell phones, these are the proportion of the population, then they would be:
38 * 58% = 22.04 students
Now, the sample proportion is 24.
Therefore 22.04 < 24
Which means the sample proportion is higher
Answer:
a. AB = 6
b. m<F = 70°
Step-by-step explanation:
a. Triangle ABC is an equilateral triangle because all three angles are equal to 60° each. Therefore, all three sides would also be equal to each other.
Thus, since one of the sides, BC = 6, therefore:
AB = BC = 6
b. The markings indicate that two sides of ∆EDF (ED & EF) are equal in length. This means that ∆EDF is an isosceles having two equal base angles (<F and <D).
This:
m<F = (180 - m<E)/2
m<F = (180 - 40)/2
m<F = (140)/2
m<F = 70°
