Answer:
b) 10
Step-by-step explanation:
(3×10+46)+14 = 90

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:
19 691 miles
Step-by-step explanation:
Last year, it drove 100%, which is 196,910. This year, it drove 90% lesser, so it actually only drove: 100% - 90% = 10%.
10% as a fraction is 
.
Distance travelled this year = × 196 910
= 19 691 miles
Answer:
<h3>∠1 = 119°</h3>
Step-by-step explanation:
We know,
The measure of exterior angle is the measure of 2 interior angles.
So,
<h3>According to the question</h3>
So,
Therefore ∠1 = 119°

Answer:
Step-by-step explanation:
(a - b)² = a² - 2ab + b²
a = 0.1x
b = 0.2y
(0.1x - 0.2y)²= (0.1x)² - 2*0.1x*0.2y + (0.2y)²
= (0.1)²x² - 0.04xy + (0.2)²y²
= 0.01x² - 0.04xy + 0.04y²
