The price of fruits per kg are given below- Watermelon Rs 18.50 Cherry Rs 72 Grapes Rs 120.60 Apples Rs 78.40 Karan bought 412 k

Papessa [141]

Answer:

$X=-2.74*10^{-7}Rs$

Step-by-step explanation:

From the question we are told that:

Table for price per Kg

Watermelon Rs 18.50

Cherry Rs 72

Grapes Rs 120.60

Apples Rs 78.40

Karan Bought:

412 kg watermelon

1 kg 200g cherries

250 g grapes

134 kg apples

Generally the equation for Total Price of Fruits Bought is mathematically given by

\sum (Price Rs* Weight kg )

$\sum (P* W)=(412*18.5)+(1.2*72)+(0.25*120.60+(134*78.40))$

$\sum (P* W)=27374289.78$

Therefore the Amount of Money he gets back is

$X=500-\sum (P* W)$

$X=-2.74*10^{-7}Rs$

Therefore

He owes the shop keeper 2.74 million Rs

Mikaela and Viktoria both competed in a curling match on opposing teams. Mikaela

mamaluj [8]

Answer:

Mikaela's team scored 5.3 points, in whole number form 5.

Step-by-step explanation:

If Viktoria's team's score was 7, 2 more than twice is (7*2) +2.

(7*2)+2=16

16 is three times Mikaela's team's score. Reduced by three means just to divide.

16/3=5.3

Mikaela's team scored 5 points.

Hope this helps!

If not, I am sorry.

The Environmental Protection Agency records data on the fuel economy of many different makes of cars. Data on the mileage of 20

artcher [175]

Answer:

A) 8.5 miles per gallon

Step-by-step explanation:

Given

$x = \{12\ 13\ 15\ 16\ 16\ 17\ 18\ 18\ 19\ 19\ 20\ 20\ 22\ 23\ 24\ 26\ 26\ 27\ 27\ 29\}$

$n = 20$

Required

The IQR

This is calculated as:

$IQR = Q_3 - Q_1$

Calculate $Q_1$

$Q_1 = \frac{1}{4}(n + 1)th$

$Q_1 = \frac{1}{4}(20 + 1)th$

$Q_1 = \frac{1}{4}(21)th$

Remove bracket

$Q_1 = 5.25th$

This means that:

$Q_1$ is the mean of 5th and 6th item

From the given data:

$5th \to 16$

$6th \to 17$

So, we have:

$Q_1 = \frac{1}{2}(16 + 17)$

$Q_1 = \frac{1}{2}(33)$

$Q_1 = 16.5$

$Q_1 = 16.25$

Calculate $Q_3$

$Q_3 = \frac{3}{4}(n + 1)th$

$Q_3 = \frac{3}{4}(20 + 1)th$

$Q_3 = \frac{3}{4}(21)th$

Remove bracket

$Q_3 = 15.75th$

This means that:

$Q_3$ is the mean of 15th and 16th item

From the data:

$15th \to 24$

$16th \to 26$

So:

$Q_3 = \frac{1}{2}(24 + 26)$

$Q_3 = \frac{1}{2}(50)$

$Q_3 = 25$

Recall that:

$IQR = Q_3 - Q_1$

$IQR = 25 -16.5$

$IQR = 8.5$
