5t/13 = -9
5t = -9 * 13
5t = -117
t = -117/5
Answer:
A) 0.26
B) 0.42
Step-by-step explanation:
No. of cars which needed both:
92 + 136 - (200 - 24)
52
P(both) = 52/200 = 0.26
No. of cars that need an alternator, but not new brakes:
136 - 52
84
P = 84/200 = 0.42
Answer:
154 students
Step-by-step explanation:
First get the total number of students .
This can be gotten by
12% of A = 21
Where A represents the total number of students.
12% represents the % of A that chose to study French and 21 is the number of students that studied French .
Therefore,
12% /100% x A = 21
0.12 x A = 21
Divide both sides by 0.12
0.12/0.12 x A = 21/0.12
A = 175
The total number of students is 175.
If 21 chose to study French their freshman year ,number of students that chose not to will be total number of students minus number of those who chose to study French.
That’s
175 - 21
= 154
154 students chose not to study French their freshman year
Answer:
y = (1/2)x + 0
Step-by-step explanation:
The equation would be y = mx + b
m is the slope and b is the y-intercept
Draw a graph of the temperatures; if the points form a straight line, then the temperatures vary directly , Option B is the correct answer.
<h3>What is Direct Variation ?</h3>
When a quantity of one variable is increased and the value of the other also increases then they are said to be in direct variation.
For the data to be in direct variation
Draw a graph of the temperatures; if the points form a straight line, then the temperatures vary directly.
The points in any linear equation can only fluctuate directly, therefore all points will lie on the same line.
Option B is the correct answer.
