Answer:
32
Step-by-step explanation:
It is given that Jeff and his friend each text four classmates about an concert that is two people texts four classmates then 2×4=8 people are notified about the concert, then according to question, each 8 of them texts 4 more students from a different school about the concert, so the total number of people from the other school which are being notified about the concert will be 8×4=32.
Answer:
x = 30
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent.
∠ B ≅ ∠ E
The sum of the 3 angles in Δ CDE = 180°, thus
∠ E = 180° - (55 + 65)° = 180° - 120° = 60°
Thus
2x = 60 ( divide both sides by 2 )
x = 30
Solution:
We are given:
μ=60
σ=15.9
n=40
Therefore, the z-statistic is 1.19
The second function has a graph that is identical to that of the first function, except that it is shifted upward by 4 units.
_____
The thrust of this question is to get you to recognize that adding a constant to a function shifts its graph in the amount and direction of the constant value (positive ⇒ upward).
