Answer:
52.15
Step-by-step explanation:
52.149
Since last digit is 9,
The tenth digit, which is 4 gets rounded to 5.
Therefore answer: 52.15
Answer:
6.57 x 10 to the power of 5
Step-by-step explanation:
Answer:
The probability of 7 winners in a row = 1 / 128.
Step-by-step explanation:
That would be (1/2)^7 . The probabilities are multiplied because the events ( heads or tails) are independent.
Using a linear function, we have that:
- The rule is P(x) = 0.5x - 75.
- The total profit after selling 0 ribbons is of -$0.75.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
For this problem, when x increases by 10, the profit increases by 5, hence the slope is:
m = 5/10 = 0.5.
Then:
P(x) = 0.5x + b.
When x = 10, P(x) = -70, hence:
-70 = 0.5(10) + b
b = -75.
Hence:
- The rule is P(x) = 0.5x - 75.
- The total profit after selling 0 ribbons is of -$0.75.

let us assume that make inclination θ
with positive direction of x-axis then slope(m) of the line is given by
m=tanθ.
