Answer:

Savings = $\frac{6.99}{50}\times 254.7$ - $\frac{5.99}{50}\times 254.7$ dollars.

Step-by-step explanation:

We are given that,

Juanita usually buys 50 pounds of mulch for $6.99.

That is, total cost of 254.7 pounds of mulch = $\frac{6.99}{50}\times 254.7$ dollars.

Now, since there is sale on the price of the mulch, we have,

Price of 50 pounds of mulch on sale = $5.99

Then, price of 254.7 pounds of mulch on sale = $\frac{5.99}{50}\times 254.7$ dollars.

Thus, the savings Juanita had = Original price of 254.7 pounds of mulch - Price of 254.7 pounds of mulch on sale.

Hence, savings = $\frac{6.99}{50}\times 254.7$ - $\frac{5.99}{50}\times 254.7$ dollars.

The radius of the base of a cylinder is 28 cm and its height is 48 cm. Find the surface area of the cylinder in terms of π. 4,23

spin [16.1K]

$\bf \textit{total surface area of a cylinder}\\\\
SA=2\pi r(h+r)~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=28\\
h=48
\end{cases}\implies SA=2\pi (28)(48+28)
\\\\\\
SA=56\pi (76)\implies SA=4256\pi$

The life of light bulbs is distributed normally. The variance of the lifetime is 900 and the mean lifetime of a bulb is 520 hour

Alex73 [517]

Answer:

0.969

Step-by-step explanation:

Given that:

Mean lifetime (m) = 520 hours

Variance = 900

Hence, standard deviation (s) = √900 = 30

Probability that bulb will last for at most 576 hours

X ≤ 576

Obtain the standardized score :

Using the relation :

Zscore = (x - m) / s

Zscore = (576 - 520) / 30

Zscore = 56 / 30

Zscore = 1.867

P(Z ≤ 1.867) : using the z probability calculator ;

P(Z ≤ 1.867) = 0.96905

Hence, P(Z ≤ 1.867) = 0.969
