<span>Evaluate ƒ(–3) for ƒ(x) = –5x2 + 2x –1.
</span>ƒ(x) = –5x2 + 2x –1
First, Substitute x by -3 in the formula of the function and calculate as follows.
ƒ(-3) = –5x2 + 2x –1
Apply the Order of Operations.
ƒ(-3) = –5(-3)^2 + 2(-3) –1
Simplify
ƒ(-3) = –5(9) + 2(-3) –1
ƒ(-3) = –45 -6 –1
ƒ(-3) = -52
Therefore, The function of ƒ(–3) for ƒ(x) = –5x2 + 2x –1 is -52
Answer:
clearly the value of the test statistics shows that there are no enough evidence to support the claim that the proportion of the grads are the same.
Step-by-step explanation:
lets prove the statement by counter example, where if we have found the statement to be false for one then we conclude that it is false for all.
first lets explain what proportion is all about; proportion can be explained as the numerical relationship that compares things together.
in particular lets take grade A proportional to grade B which implies that 18:20
clearly if we observe here grade A is not same proportion with grade B. hence we conclude that there are no enough evidence to support the professor's claim.
Answer:
Step-by-step explanation:
This is a binomial probability distribution because there re only 2 possible outcomes. It is either a surveyed company outsourced some part of their manufacturing process in the past two to three years. The probability of success, p would be that a randomly selected company x, outsourced some part of their manufacturing process in the past two to three years. From the information given, p = 54/100 = 0.54
Number of success, x = 338
Number of samples, n = 555
We want to determine the probability that 338 or more companies outsourced some part of their manufacturing process in the past two or three years which is expressed as
P(x ≥ 338)
From the binomial probability calculator,
P(x ≥ 338) = 0.0006
The percentage is 0.0006 × 100 = 0.06%
A quadratic equation is a parabola and a linear equation is a line. A line and a parabola may intesect 0, 1, or 2 times.
