Volume = l*b*h

1. Ans 24 unit cubes

Because it had 6 unit cubes as length, 2 unit cunes as breadth and 2 unit cubes as height.

2. Volume = l*b*h
= 30*15*4
=1800 cubic feet

The first one is 24 unit cubes because all you need to do is count the amount of cubes the cuboid has. Unfortunately I have no idea how to do the second one

The body temperatures of adults have a mean of 98.6°F and a standard deviation of 0.60° F. Describe the center and variability o

amid [387]

Answer:

center = 98.6, variability = 0.08

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sample means with size n of at least 30 can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$

The center is the mean.

So $\mu = 98.6$

The standard deviation of the sample of 50 adults is the variability, so

$s = \frac{0.6}{\sqrt{50}} = 0.08$

So the correct answer is:

center = 98.6, variability = 0.08

There is no graph to support the statement and so, this invisible graph is misleading :)

Use the integer tiles to evaluate the following expressions. 6 + 3 = 6 + (–4) = 6 + (–6) =

babunello [35]

Given:

The expressions are:

$6+3$

$6+(-4)$

$6+(-6)$

To find:

The value of given expression by using integer tiles.

Solution:

We have,

$6+3$

Here, both number are positive. When we add 6 and 3 positive integer tiles, we get 9 positive integer tiles as shown in the below figure. So,

$6+3=9$

Similarly,

$6+(-4)$

Here, 6 is positive and -4 is negative. It means we have 6 positive integer tiles and 4 negative integer tiles.

When we cancel the positive and negative integer tiles, we get 2 positive integer tiles as shown in the below figure. So,

$6+(-4)=2$

$6+(-6)$

Here, 6 is positive and -6 is negative. It means we have 6 positive integer tiles and 6 negative integer tiles.

When we cancel the positive and negative integer tiles, we get 0 integer tiles as shown in the below figure. So,

$6+(-6)=0$

Therefore, $6+3=9, 6+(-4)=2,6+(-6)=0$ .

Please help I learned this a while ago and forgot how to do it

Answer:

The slope-intercept form is $y=\frac{1}{2}x+\frac{11}{2}$

Step-by-step explanation:

To find the slope, use

$m=\frac{y^2-y^1}{x^2-x^1}$

Replace the x and y values with the points.

$m=\frac{7-5}{3-(-1)}$

Solve.

$m=\frac{2}{4}$

$m=\frac{1}{2}$

After that, find the y-intercept form.

Put the equation in point-slope form.

$y-5=\frac{1}{2}(x+1)$

Replace x with 0.

$y-5=\frac{1}{2}(0+1)$

$y-5=\frac{1}{2}$

Add 5 to both sides.

$y=5\frac{1}{2}$

Convert to improper fraction form.

The y-intercept is $\frac{11}{2}$

Now finally, write in slope-intercept form. (y=mx+b)

m is slope, b is the y-intercept.

Translate the following statement to an inequality. A number is at most seven. x > 7 x < 7 x ≥ 7 x ≤ 7

damaskus [11]

The required inequality is: x≤7

Step-by-step explanation:

The words have to be considered and observed properly to write an inequality.

At most means, that the value cannot exceed 7.

So,

Let x be a number

Then

A number is at most 7 will be written as:

$x\leq 7$

as the value of x cannot exceed 7.

The required inequality is: x≤7
