Answer:

There is 1 solution (1,0)

Step-by-step explanation:

y = 3.5x − 3.5

y = −3.5x + 3.5

Add this system of equations together

y = 3.5x − 3.5

y = −3.5x + 3.5

-----------------------

2y = 0

y = 0

Substitute back in

0 = 3.5x - 3.5

Add 3.5 to each side

3.5 = 3.5x

Divide by 3.5

3.5/3.5 = 3.5x/3.5

1=x

There is 1 solution (1,0)

How do I solve part b and c

OLEGan [10]

Answer:

part a: 52%

part b: 0.4

part c: 0.24

Step-by-step explanation:

For part one, you find the frequency of the number of people that are less that 20. You add the number of tics in each bar and you divide by the total.

so for part a it is (7+6+9+4)/ (7+6+9+4+4+12+8)

for part b you add up the values that are greater than 25(less than 35)

(12+8)/total

part c you find the number of people between 25 and 30

that's 12

over total

12/total

Jamie takes at random a counter from the bag and records the colour. Red : blue : green = 1:3:7 Jamie does this a number of time

Sonbull [250]

Answer: There are 249 times Jamie takes a counter from the bag.

Explanation:

Since we have given that

Ratio of colour of red to blue to green is 1:3:7.

Number of blue counters = 68

Let the total number of times Jamie does from the bag be x.

So, According to question,

$\frac{3}{11}\times x=68\\\\x=\frac{11}{3}\times 68\\\\x=249.33\\\\=249\ approx.$

Hence, there are 249 times Jamie takes a counter from the bag.
