No because it would have to be 3.50 to be equivalent
Answer:
add them then multiply
Step-by-step explanation:
To solve this
problem, we will have to make use of the z statistic. The formula for the z
score is given as:
z = (x – u) / s
where,
x is the sample value = more than $10.00
u is the sample mean = $8.22
s is the standard deviation = $1.10
Substituting the values into the equation to solve for z:
<span>z = (10 – 8.22) /
1.10</span>
z = 1.78 / 1.10
z = 1.62
We then look for the p value using the standard
distribution tables at the specified z score value = 1.62. Since this is a
right tailed test, therefore the p value is:
p = 0.0526
or
p = 5.26%
<span>Therefore there is a 5.26% probability that a household
spent more than $10.00</span>
Answer:
= - 119973
Step-by-step explanation:
The sum to n terms of a geometric sequence is
=
where a is the first term and r the common ratio
Here a = - 3 and r = 18 ÷ - 3 = - 6 , thus
=
=
=
= - 119973
Answer:
Step-by-step explanation:
<u>The volume of the box:</u>
<u>Substitute values:</u>
- V = 3 1/4 × 3 × 1 = 13/4 × 3 = 39/4
<u>The volume of each block:</u>
<u>Number of blocks that the box can fit:</u>
- 39/4 ÷ 1/64 = 39/4 × 64 = 39 × 16 = 624
Correct choice is C
