Nick = n
Ray = r

n=3r-30
n+r=74

3r-30+r=74
4r-30=74
4r=104
r=26
n=26*3-30
n=78-30
n=48
Nick is 48 years old and Ray is 26 years old
Hope this helps.

If you know that a < b, and both a and b are positive numbers, then what must be true about the relationship between the oppo
Ymorist [56]

Answer:

The number further left on a number line is the smaller number. For positive numbers, the number closest to zero is smaller. For negative numbers, the number closest to zero is larger. If a is less than b, and they are both positive, then a is closer to 0 than b. The opposite of a is also closer to zero than the opposite of b, so the opposite of a must be larger than the opposite of b.

A hockey coach recorded the number of shots taken by the home team and the number taken by the visiting team in 20 games. He dis
Harrizon [31]

Answer:

The most accurate inference from this boxplot is that: The visiting team had more variability in the number of shots taken.

Step-by-step explanation:

The box and whiskers plot is a way of presenting data that gives 5 major information about the distribution

From the whiskers of the plot, one can read

- The minimum value

- The maximum value

Then, from the boxplot, one can read

- The Median, represented by the middle line of the boxplot.

- The first Quartile or 25th percentile, represented by the lower end of the boxplot.

- The third quartile or 75th percentile, represented by the upper end of the boxplot.

Other variables that can be obtained from these five data points include

- The range of the distribution (maximum value minus minimum value)

- The interquartile range (a measure of variation, which is the difference between the third and first quartile of the distribution)

For the two boxplots that the coach made

Home team

Whiskers range from 16 to 32

Minimum value = 16

maximum value = 32

the box ranges from 20 to 23. A line divides the box at 22.

First quartile = 20

Third quartile = 23

Median = 22

IQR = 23 - 20 = 3

For the visiting team

Whiskers range from 14 to 32

Minimum value = 14

maximum value = 32

the box ranges from 16 to 24. A line divides the box at 18.

First quartile = 16

Third quartile = 24

Median = 18

IQR = 24 - 16 = 8

Since the median only represents the midpoint of the distribution, one cannot conclude with certainty that home team took more shots than the visiting team, information on the mean would confirm that.

A less controversial and evident inference is that the visiting team had more variability in their shots as their distribution has a higher Interquartile Range (IQR of 8 > 3) which is a direct measure of variation for distributions.

Hope this Helps!!!

Quadrilaterals WXYZ and BADC are congruent. In addition, WX ≅ DC and XY ≅ BC. If AD = 4 cm and AB = 6 cm, what is the perimeter
Yanka [14]

If <u>quadrilaterals</u> WXYZ and BADC are <u>congruent</u>, then their corresponding <u>sides</u> are congruent.

Given that

  • WX≅DC,
  • XY≅BC,

you can state that

  • YZ≅AB,
  • WZ≅AD.

If AD = 4 cm and AB = 6 cm, then WZ = 4 cm and YZ = 6 cm. Opposite rectangle sides are congruent, then XY = 4 cm and WX = 6 cm.

The perimeter of WXYZ is

P = WX + XY + YZ + WZ = 6 + 4 + 6 + 4 = 20 cm.

Answer: 20 cm

Select the correct interpretation of the probability of getting an 11 when a pair of dice is rolled. Interpret an event as signi
klio [65]

Answer:

c. Not significant at .055

Step-by-step explanation:

When a pair of dice is rolled, we have 6²=36 possible outcomes. Only 2 of these outcomes have a total score of 11:

  1. When the first dice is 5 and the second is 6.
  2. When the first dice is 6 and the second is 5.

Then, we can calculate the probability of getting 11 as the quotient between the successs outcomes and the total outcomes.

Then, the probability of getting 11 is:

P=\dfrac{X}{N}=\dfrac{2}{36}=0.055

This probability is not equal or less than 0.05, so it is not significant at 0.055.

Tamiku [17]

Answer:

Lance will arrive at the airport at 10:00 AM.

Step-by-step explanation:

Lance left his house at 6:00 AM, and drove to the airport, which is 220 miles away, at 55mph; therefore, the time t it takes Lance to cover the distance of 220 miles is

t = \dfrac{220m}{55mph}

t= 4 \: hours.

Thus, it takes Lance 4 hours to reach the airport, and since he departed at 6:00 AM, he will arrive at the airport at (6+4):00 AM + 10:00 AM.
