Answer:

$5.99 for 1.5 lbs of gumballs

Step-by-step explanation:

You want to buy One and a half pounds of gumballs for $3.99 per pound. It is 3.99 for one pound of gumballs, so the price for half a pound of gumballs is half of that price.

3.99 / 2 = 1.995

Then add the price of 1 pound

3.99 + 1.995 = 5.985

Then you can round that up to 5.99

Which events are independent? Check all that apply. rolling two number cubes at the same time choosing a card, and then flipping

klemol [59]

Independent events are such events where the occurrence of any one event does not affect the occurrence of any other event.

Part A: rolling two number cubes at same time does not affect outcome of any one cube. It would be Independent events.

Part B: choosing a card, then flipping a coin according to favourable outcome can affect the result. It would be dependent events.

Part C: choosing a winner, keeping it, then choosing another name depends upon remaining persons. It would be dependent events.

Part D: drawing a marble, replacing it, then drawing another marble does not affect number of marbles in the bag. It would be Independent events.

Part E: flipping any coin three times does not affect past or future outcomes. It would be Independent events.

Hence, options A, D, and E are Independent events.

Dmitry [639]

Answer:

Answer: C.Fraction 11 and 1 over 4 cubic inches

Step-by-step explanation:

The volume of a rectangular prism of length L, width W, and height H is given by:

V=LWH

The prism is packed with cubes of a side length of a=1/2 inch. The volume of each cube is:

$V_c=a^3=\left(\frac{1}{2}\right)^3=\frac{1}{8}\ in^3$

The prism is packed with L=5, W=3, and H=6, thus the volume (in cubes) is:

V=5*3*6=90\ cubes

Since each cube has a volume of $\frac{1}{8} in^3$ :

$V=90\cdot\frac{1}{8}=\frac{45}{4}$

Expressing as a mixed fraction:

$V=\frac{45}{4}=\frac{44+1}{4}=11\frac{1}{4}$

Answer: C.Fraction 11 and 1 over 4 cubic inches

About % of the area under the curve of the standard normal distribution is between z = − 0.9 z = - 0.9 and z = 0.9 z = 0.9 (or w

prisoha [69]

Using the normal distribution, it is found that 63.18% of the area under the curve of the standard normal distribution is between z = − 0.9 z = - 0.9.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The area within 0.9 standard deviations of the mean is the p-value of Z = 0.9(0.8159) subtracted by the p-value of Z = -0.9(0.1841), hence:

0.8159 - 0.1841 = 0.6318 = 63.18%.
