Answer:

The option "C" is correct

#in my opinion#

Step-by-step explanation:

The size of a screen is generally measured diagonally.

Thus to find the diagonal length,

we take help from Pythagoras theorem

$i.e. \\ {h}^{2} = {b}^{2} + {p}^{2}$

where h (hypotenuse) is the diagonal length, b (base) is the length of horizontal side, and p (perpendicular) is the length of the vertical side of the TV,

THUS the diagonal length or hypotenuse

$h = \sqrt{ {b}^{2} + {p}^{2} } \\ \: = \sqrt{1024 + 324} \\ \: = \sqrt{1348} \\ \: = 36.7 \: (= aprox \: 37)$

Write an equality that represents eight less that three times a number is more than 22

leonid [27]

Answer:

3x - 8 > 22

Step-by-step explanation:

" eight less" means to subract 8 form something. If you had 10 apples and I took some so now you had 8 less apples, you'd have 10 - 8 = 2 apples

"three times a number" means 3x. 3 times some number.

The expression 3x - 8 means "8 less than 3 times a number"

"is" is math is a statement of equality, either an equals sign or an inequality needs to go here.

Our inequality is

3x - 8 > 22

Answer:

The discount is $0.8d.

Step-by-step explanation:

Given that,

The original cost of Tamara's purchase is d dollars.

Tamara uses a coupon to save 20% off her purchase at the bookstore.

Discount = 20%

Discount is applied to the original cost.

Discount = d-(20/100)d

Discount = 0.8 d

Hence, the discount is $0.8d.

The data set represents the number of rings each person in a room is wearing. 0, 2, 4, 0, 2, 3, 2, 8, 6 What is the interquartil

forsale [732]

Answer:

$IQR=4$

Step-by-step explanation:

We have been given a data set that represents the number of rings each person in a room is wearing as: 0, 2, 4, 0, 2, 3, 2, 8, 6. We are asked to find the interquartile range of the data.

Let us arrange our data points from least to greatest order.

0, 0, 2, 2, 2, 3, 4, 6, 8.

Let us find median of our data set. Since our data set has 9 data points, therefore, median of our given data set will be value of 5th term, that is 2.

Now let us find lower quartile, which is also known as the median of the data points to the left of median.

We have 4 data points to the left of our median, so our lower quartile will be average of 2nd and 3rd data point.

$Q_1=\frac{0+2}{2}=\frac{2}{2}=1$

Now let us find upper quartile of our given data set, which is the median of the data points to the right of median.

We have 4 data points to the right of the median, so our upper quartile will be the average of 7th and 8th data point.

$Q_3=\frac{4+6}{2}=\frac{10}{2}=5$

Since we know that interquartile range is the difference between upper and lower quartile.

$IQR=Q_3-Q_1$

$IQR=5-1$

$IQR=4$

Therefore, IQR of our given data set is 4.
