Answer:
Shyla's have not done any mistake.
Step-by-step explanation:
We have given that, The explicit rule for the series 0, 1, 2, 3, ... is given by 
.
Shyla's attempt to find the fifth term in the sequence is shown below:
i.e. substitute n=5
Looking at the sequence, the 4th number would be 3.
According to explicit rule the fourth term is
Which is correct.
Similarly all the terms will get in this way.
So, Shyla's have not done any mistake.
The bell curve attached below shows the normal distribution of the data.
We are looking the value of X such as the area to its left gives the probability of 0.75
We first need the z-score which we can obtain by reading from the z-table (as shown in the second picture below)
The z-score is = 0.7734
Then we use the following formula to work out X
z-score = (X - Mean) ÷ Standard Deviation
0.7734 = (X - 100) ÷ 15
0.7734×15 = X - 100
11.601 = X - 100
X = 11.601 + 100
X = 111.601 ≈ 112
Hence the third quartile is 112
Answer:
B
Step-by-step explanation:
pi / 2 is equal to 180°/2 which is 90°.
Cos (90°) = 0
if cos90 = 0 then what kind of graph will we have at 90° to the x axis ?
a graph passing through the origin. (0,0)
So how much does she spend in all right
