The box plots below show the average daily temperatures in July and August for a U.S. city:
Over [174]
The correct answer would be option A.

The maximum value of the Temperatures in August is greater than the median of the July Temperatures. The box plot only gives us the idea about the distribution/spread of the data. It does not highlight the frequency of the values in the data set.

It is possible that the maximum temperature in August occurs on a lot many days. As a result the mean temperature will be higher. Similarly, the lower temperature in July can occur more frequently. So this is possible that mean temperature in August is higher than that of July.

Chances are more that the mean temperature in July was higher, but there is a possibility of the mean temperature to be higher in August. So we can not conclude about the means by surety.

Therefore, option A is the correct answer

A light bulb consumes 2400 watt-hours per day. how long does it take to consume 9000 watt- hours?
Luden [163]

Answer:

3.75

Step-by-step explanation:

Set up the following ratio:

2400 watt-hours           1 day

-------------------------   =    ----------

9000 watt-hours           x days

Then do criss-cross-apple-sauce:

x*2400=9000*1

And then solve for x:

2400x=9000

x=9000/2400

x=3.75

At the farmers market a farmer has bunches of radishes for sale. The
stealth61 [152]

Answer:

The  probability a random selected radish bunch weighs between 5 and  6.5 ounces is 0.8185

Step-by-step explanation:

The  weight of the radish bunches is normally distributed with a mean of  6 ounces and a standard deviation of 0.5 ounces

Mean = \mu = 6

Standard deviation = \sigma = 0.5

We are supposed to find  the  probability a random selected radish bunch weighs between 5 and  6.5 ounces i.e.P(5<x<6.5)

Z=\frac{x-\mu}{\sigma}

At x = 5

Z=\frac{5-6}{0.5}

Z=-2

Z=\frac{x-\mu}{\sigma}

At x = 6.5

Z=\frac{6.5-6}{0.5}

Z=1

Refer the z table for p value

P(5<x<6.5)=P(x<6.5)-P(x<5)=P(Z<1)-P(Z<-2)=0.8413-0.0228=0.8185

Hence the  probability a random selected radish bunch weighs between 5 and  6.5 ounces is 0.8185

If we apply the Pythagorean Theorem to the Egyptian knots we can see that 3^2 + 4^2 = 5^2. Which of the sets of three numbers li
Anestetic [448]

Answer: the answers are c and d

Step-by-step explanation: only these combinations would form right triangles because the way other combinations are too small or too large to actually accommodate for the remaining number in the problem. The squares of 5, 12, and 13 are 25, 144, and 169, meaning they form a perfect right triangle. The next sequence is 36, 85, 77, and the squared rearranged version is 1,296, 5,929, and 7,225, meaning they also form a right triangle.
