Answer:
x=120 is the answer it is hard to described without name
Answer:
x = 85°
Step-by-step explanation:
Because the sum of the angles in a triangle is 180°, we can find ∠CDB.
180° - ∠CBD - ∠BCD = ∠CDB.
180° - 35° - 50° =
180° - 85° =
95°
So, ∠CDB is 95°
Then, because a line has 180°, we can find ∠CDA.
180° - ∠CDB = ∠CDA.
180° - 95° = 85°
So, x = 85°
Answer:
0.998 is the probability that the average money spent by a sample of 40 shoppers is within $10 of the actual population mean.
Step-by-step explanation:
We are given the following information in the question:
Standard Deviation, σ = $21.51
We are given that the distribution of average money spend is a bell shaped distribution that is a normal distribution.
Formula:

We have to find:
P( average money spent is within $10 of the actual population mean.)

Calculation the value from standard normal z table, we have,

8 1-and-a-half blocks would be 12 blocks, and so 12/17, because 12 blocks in 17 mins., so you divide 12 by 17 to get ---- blocks per minute, which is 12/17 as a fraction, or approx. 0.705882353 blocks per minute.
