Answer:

5ft^3

Step-by-step explanation:

The formula for volume is length × width × height.

so you multiply 1×2×2.5, which equals 5

Answer: The standard error of the mean = 0.5

Step-by-step explanation:

Given : Sample size : n = 144

Standard deviation : $\sigma=6\text{ hours}$

The formula to find the standard error of the mean is given by :-

$S.E.=\dfrac{\sigma}{\sqrt{n}}$

i.e. $S.E.=\dfrac{6}{\sqrt{144}}=0.5$

Hence, the standard error of the mean =0.5

JUUL Practice & Problem Solving 7.4.PS-10 Question Help Find the area of the polygon in square units. 4 2 e - 8 -6 - 4 - 2 4

V125BC [204]

area formula is

$A=\frac{1}{2}(b1+b2)h$

where:

b1 = small base

b2 = large base

h = height

then solve:

$A=\frac{1}{2}(2+6)3=\frac{1}{2}(8)3=\frac{24}{2}=12$

asnwer: 12 square units

Malachai is doing a 20 miles bike ride. He has cycled 11 miles so far. What percentage of the the total distance has he cycled

Anestetic [448]

11 miles / 20 miles =.55
.55 x 100 = 55%
11/20 is the proportion and you multiply by 100 to gey a percent
another way to solve is
11/20 x 5/5 = 55/100 = 55%
you multiply by 5/5 because it is equal to one and it makes the denominator equal to 100 it also follows the rule that whatever you do to the top you must do with the bottom

5. Please write the equation of a line in y=mx+b format. Find the SLOPE first then find the Y-INTERCEPT (b) Your answer

castortr0y [4]

Answer:

y = $\frac{5}{3}x-1$

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Here m = slope of the line

b = y-intercept

Slope of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is,

m = $\frac{y_2-y_1}{x_2-x_1}$

From the graph attached,

Since, the given line passes through (0, -1) and (3, 4),

Slope 'm' = $\frac{4+1}{3-0}$

m = $\frac{5}{3}$

y - intercept 'b' = -1

Therefore, equation of the line will be,

y = $\frac{5}{3}x-1$
