<span>(3 x 1000) + (16 x 10) + (7 x 1) = 3167. In standard form, this is 3.167 x 10^3. </span>
Answer:
The answer is 292.8
Step-by-step explanation:
You just have to divided 1464 by 5
The formula for z-score is:
z-score = (X – μ) / σ
where,
X = sample
μ = mean =
1001
σ = standard
deviation = 6
Since we are
looking for volumes less than 1001 mL, let us use 1000.5 mL for X.
z-score =
(1000.5 – 1001) / 6
z-score =
-0.083
Referring to
the standard distribution table for z-test, this corresponds to:
p = 0.4681
<span>So 46.81% of
the bottles are less than 1001 mL.</span>
Let X be the number of hours
Brady drives 60 mph for X number of hours, which is written as 60x.
Mary drives 45 mph for x number of hours, which is written as 45x.
The equation to solve for the number of hours is:
60x + 45x = 1365
Simplify:
105x = 1365
Divide both sides by 105:
x = 1365 / 105
x = 13 hours.
