How can you determine the shape of a graph

1 answer:

agasfer [191]2 years ago

4 0

Answer:

The four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. A graph with a single peak is called unimodal. A single peak over the center is called bell-shaped. And, a graph with two peaks is called bimodal.

Step-by-step explanation:

The mean amount spent by a family of four on food is $500 per month with a standard deviation of $75. Assuming that the food cos

Alexeev081 [22]

Answer:

$z=\frac{x- \mu}{\sigma}$

And replacing we got:

$z=\frac{425-500}{75}= -1$

And we can calculate this probabilit using the normal standard distribution or excel and we got:

$P(z$

Step-by-step explanation:

If we define the random variable of interest "the amount spent by a family of four of food per month" and we know the following parameter:

$\mu = 500, \sigma = 75$

And we want to find the following probability:

$P(X$

And we can use the z score formula given by:

$z=\frac{x- \mu}{\sigma}$

And replacing we got:

$z=\frac{425-500}{75}= -1$

And we can calculate this probabilit using the normal standard distribution or excel and we got:

$P(z$

What is the volume of the cylinder below?

lbvjy [14]

$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's solve ~

We need to find volume of the given Cylinder, with information :

radius (r) = 12 units

height (h) = 17 units

$\qquad \sf \dashrightarrow \:Volume_{(Cylinder)} = \pi r²h$

$\qquad \sf \dashrightarrow \:Volume_{(Cylinder)} = \pi \sdot(12) {}^{2} \sdot17$

$\qquad \sf \dashrightarrow \:Volume_{(Cylinder)} = \pi \sdot144{}^{} \sdot17$

$\qquad \sf \dashrightarrow \:Volume_{(Cylinder)} = 2448 \pi \: \: unit {}^{3}$

So, correct choice is B

What is the best approximation for the circumference of a circle with a radius of 125 m?

ANEK [815]

Answer:

Option B is correct

circumference of a circle is 785 m

Step-by-step explanation:

Circumference of the circle(C) is given by:

$C = 2\pi r$

where

r is the radius of the circle

As per the statement:

radius of the circle is 125 m

then substitute in [1] we have

$C = 2 \cdot 3.14 \cdot 125$

Simplify:

C = 785 m

Therefore, the circumference of a circle is 785 m
