Answer:

Step-by-step explanation:

$1) Sin \ C = \dfrac{opposite side of C}{Hypotenuse}=\dfrac{21}{29}\\\\2)Sin \ C = \dfrac{30}{50}=\dfrac{3}{5}\\\\3) Cos \ C = \dfrac{adjacent \ side \ of \ C}{hypotenuse}=\dfrac{36}{39}=\dfrac{12}{13}\\\\4) Cos \ C =\dfrac{8}{17}$

Given f(x) is a linear function with slope 3 and y-intercept -5, what is the equation of f(x) in standard form?

lawyer [7]

The standard form:

$Ax+By=C$

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

We have m = 3 and b = -5.

Substitute:

$y=3x-5$ subtract 3x from both sides

$-3x+y=-5$ change the signs

$3x-y=5$

The owner of a fish market has an assistant who has determined that the weights of catfish are normally distributed, with mean

LiRa [457]

Answer:

$P(X\geq 3.4)=0.0228$

Step-by-step explanation:

Given the mean is 3.2, standard deviation is 0.8 and the sample size is 64.

-We calculate the probability of a mean of 3.4 as follows:

#First determine the z-value:

$z=\frac{\bar X -\mu}{\sigma/\sqrt{n}}\\\\=\frac{3.4-3.2}{0.8/\sqrt{64}}\\\\=2.000$

#We then determine the corresponding probability on the z tables:

$Z(X\geq 3.4)=1-P(X$

Hence, the probability of obtaining a sample mean this large or larger is 0.0228

Which of these functions had a greater rate of change than the function graphed below, and why?

Mrac [35]

Answer:

Step-by-step explanation:

When we talk of rate of change, we talk of the slope of the line

If we had a line;

y = mx + b

m is the slope ( which is the rate of change)

To get the slope of the line, we select any two points on the line and apply the slope formula

m = y2-y1/x2-x1

let us take points (0,0) and (3,9)

m = 9-0/3-0 = 9/3 = 3

The slope here is 3

so from the option, we can see that the third option is the correct answer
