Pavlova-9 [17]

Complete Question:

Jenny is going to tile her kitchen floor of area 30 m^2. She has taken out all the furniture and appliances. Jenny wants to know if she has got enough money to buy the tiles.The tiles are sold in packs, which cover 2m2 Jenny has a discount card which gives her 25% off any marked price at the DIY shop. The tiles are marked at £9.60 Jenny has £100 to spend on the tiles. How much extra does Jenny need to buy the tiles? Give your answer in pence.

Answer:

Extra amount needed by Jenny to buy the tiles = £8

Step-by-step explanation:

Floor area = 30.0 m^2

Area covered by a pack of tiles = 2.0 m^2

Number of packs needed = 30/2

Number of packs needed = 15

Price of a pack of tiles = £9.60

Discount = 25%

Jenny will pay 75% of the marked price

Amount Jenny will pay for a pack of tiles = 75% of 9.60 = 0.75*9.60

Amount Jenny will pay for a pack of tiles = £7.20

Amount Jenny will pay for 15 packs of tiles = 7.20 x 15

Amount Jenny will pay for 15 packs of tiles = £108

The amount of money Jenny currently has = £100

Extra amount needed by Jenny to buy the tiles = £108 - £100

Extra amount needed by Jenny to buy the tiles = £8

BartSMP [9]

True because if you are multiplying any number by a fraction smaller than 1, you are practically dividing it so the number become smaller. For example, multiplying by 1/2 is findind the half so its gonna get smaller.

The number of defects in the first five cars to come through a new production line are 9, 7, 10, 4, and 6, respectively. If the

garri49 [273]

Answer:

D. I and III only

Step-by-step explanation:

Number of first fie defects are given as 9,7,10,4 and 6.

First we have to arrange the above data in ascending order which is 4,6,7,9,10

Now if we consider the defect in sixth car to be 3 then our data will look like: 3,4,6,7,9,10

So the mean of above data would be $\frac{3+4+6+7+9+10}{6}$ = 6.5

and Median of the above data would be = $\frac{3^{rd} obs + 4^{th} obs}{2}$ = $\frac{6+7}{2}$ = 6.5

Hence mean and median number of defects are same if the sixth car has 3 defects.

Now if we consider the defect in sixth car to be 12 then our data will look like: 4,6,7,9,10,12

So the mean of above data would be $\frac{4+6+7+9+10+12}{6}$ = 8

and Median of the above data would be = $\frac{3^{rd} obs + 4^{th} obs}{2}$ = $\frac{7+9}{2}$ = 8

Hence mean and median number of defects are same if the sixth car has 12 defects.

But Now if we consider the defect in sixth car to be 7 then our data will look like: 4,6,7,7,9,10

So the mean of above data would be $\frac{4+6+7+7+9+10}{6}$ = 7.167

and Median of the above data would be = $\frac{3^{rd} obs + 4^{th} obs}{2}$ = 7

Hence mean and median number of defects are not same if the sixth car has 7 defects.

Therefore option D is correct.
