Answer:

f(0)=9

Step-by-step explanation:

All you do is plug in x=0 into the function.

In this case:

f(x)=10^x+8

f(0)=10^0+8

f(0)=1+8

f(0)=9

Therefore, f(0)=9

Sam buys

Paladinen [302]

Answer:

He is wrong

Step-by-step explanation:

£1.30(cost of 1 egg box) x 2=£2.60

2.60(2 egg boxes)+2.60(price of juice)=£5.20(amount spent without baguettes)

10-5.20(amount spent without baguettes)=£4.80

4.80/3=£1.60

£1.60=cost of one baguette

Sam is wrong as the cost of one baguette is £1.60

Scott found a rare comic book on an online auction site priced at 35 Australian dollars. If the exchange rate is $1 U.S=$1.09 Au

adell [148]

1 US = 1.09 Australian

divide by 1.09 on both sides to find how much a 1 Australian dollar is worth.

1/1.09 = 1 Australian dollar
1 Australian dollar = 0.92 US dollar

mulitply 35 on both sides of the equation

35 Australian = 35 (0.92) = 32.2 US dollars

Over the first five years of owning her car, Gina drove about 12,700 miles the first year, 15,478 miles the second year, 12,675

kvv77 [185]

Answer:

Part a)

Mean: 13155.6

Mode:None

Median: 12700

Step-by-step explanation:

12700 : 1

15478: 2

12675: 3

11850: 4

13075: 5

Mean :

$=\frac{Sum of all values}{Total no. of values} \\=\frac{12700 + 15478 + 12675 + 11850 + 13075}{5}\\=\frac{65778}{5}\\= 13155.6$

Mode:

All values are distinct, therefore there is no mode. A mode is value which occurs most frequently.

Median:

Arrange the values in ascending order:

11850 , 12675, 12700, 12075, 15478

The mid value is median: 12700

Part b)

It depends upon the data. In this question the best way to predict how many miles Gina will drive in the next years is by using Median of the data.

The reason is that there is a potential outlier in the data i.e 15478. In case of outlier median tends to give better predictions.
