Answer:

Correct option is

36.25

Modal class =30−40

So we have, l=30,f0=12,f1=32,f2=20 and h=10

⇒ Mode=l+2f1−f0f2f1−f0×h

=30+2×32−12−2032−12×10

=30+6.25

=36.25

∴ Mode =36.25

Answer:

k=6

Step-by-step explanation:

Line partition formula

1/b(x2-x1)+x1, 1/b(y2-y1)+y1

Where b is the number partitions.

We know the x values so Subsitue 17 for x2 and 2 for x1. and we know this value must equal 7.

1/b(17-2)+2=7

1/b(15)=5

1/b=1/3

b=3

so the partition is 1/3

$\frac{1}{3} (17 - 2) + 2 = 7$

So let find the y coordinate

$\frac{1}{3} (8 - 5) + 5 = 6$

So our y coordinate is 6.

while swimming a 2km race, Adam changes from breaststroke to butterfly every 200m. How many times does he switch strokes during

aleksley [76]

in the first half he would have swam 1 km. there are 1000m in a km so 1000/200=5 so he swam the first 200 fly, then a 200 breast, then a 200 fly again, then another 200 breast the finish the first 1 km with a 200 fly. so we switched strokes 4 times.

PS i wouldn't recommend doing a 2 km swim fly and breast

Sara works 40 hours per week and earns $660. Which graph shows the unit rate for this situation?

coldgirl [10]

Answer: $16.5/hour

Step-by-step explanation:

The unit rate is the relationship between y and x if x = 1

660/40 = 16.5

That means, if x = 1, y = 16.5

Therefore, <u>$16.5/hour</u>
