Answer:
It will take 4.5hrs to cover the same distance
The constant of variation,k=252
Step by step explanation
Given that,

From the question
Time=4hr
Speed=63km
By substitution we obtain,

Cross multiplying we get,


Now,
speed=56km
Distance Covered=252km
By substitution:
We obtain,

Cross multiply

Divide through by 56


From the formula,

Which means that, speed and time varies inversely.

Let k be variation constant
This implies that


Taken,
Time=4hrs
speed=56km


Answer:
40%
Step-by-step explanation:
Probability that student is a male Given that it's a senior ::
Recall :
P(A | B) = (AnB) / B
Hence, we have ;
P(male | Senior) = number of (Male n Senior) / total Senoirs
From the table :
Total seniors = 2 + 3 = 5
Male n Seniors = 2
P(male | Senior) = 2 / 5 = 0.4 = 40%

Answer:
Look below
Step-by-step explanation:
lets have -29 be y2 and -5 be x2
21 - (-)29
5 - (-)5
Subtracting a negative is just adding it so
21 + 29 50
5 + 5 10
50/10
this simplified, is 5/1 or 5
y=5x+b
now we need to find b, so we substitute y and y
x = 5
y = 21
21=5*5=b
5*5 is 25
now we need to get to 21
25 -4 is 21
b = -4
y=5x-4
Well if it is a number like .933333333 you will have to round it, So now it is .93 and .93 in a fraction is 93/100
