Answer: full budget of 100% will be 1600
Step-by-step explanation:
If 75% = 1200
Full budget will be 100%
Represent the question as if 75% = 1200
Then 100% = x
Cross multiply:
75%x = 1200%
Divide both sides by 75%
x = 1200%/75%
x = 16 × 100
= 1600

Answer:
Step-by-step explanation:
(a) Approximate the population standard deviation (?) with the sample standard deviation (s)
Approximate the standard normal distribution with the Student's t distribution
--------------------------------------------------------------------------------------------------------------------------------
(b) The degree of freedom =n-1=60-1=59
Given a=0.1, t(0.05, df=59) =1.67 (from student t table)
So the lower bound is
xbar -t*s/vn =41 -1.67*3/sqrt(60) =40.35
So the upper bound is
xbar +t*s/vn =41 +1.67*3/sqrt(60) =41.65
Answer:
[6, 18]
Step-by-step explanation:
the first matrix has the dimensions 1 x 2 (1 row, 2 columns). The send has the dimensions 2 x 2. Because of this it is possible to do matrix multiplication and the result will be a 1 x 2 matrix.
Multiply the column -2, 7 by the row 4, 2:
We get (-2)(4) + (7)(2), which simplfies to 6. This is the first element of the 1 x 2 product.
Multiply the column 5, -1 by the row 4, 2: We get (5)(4) + (-1)(2), or 18.
The fourth answer choice is the correct one: [6, 18]
Step-by-step explanation:
a. 81 ÷ 9 = 9
b. 40 ÷ 5 = 8
c. 21 ÷ 3 = 7
d. 54 ÷ 6 = 9
e. 42 ÷ 7 = 6
f. 63 ÷ 9 = 7
g. 36 ÷ 4 = 4
h. 45 ÷ 9 = 5
i. 39 ÷ 3 = 12
j. 24 ÷ 6 = 4
