Answer:

V= 7.5ft x 4.2 ft x w ft

Step-by-step explanation:

TO find the volume, you follow the expression. height x width x length.

7.5 x 4.2 = 31.5

Next we will use the substituted width of 2.

31.5 x 2 = 63 ft

I would like to say that you can multiply the height, width, and length in any order due to the commutative property.

In Class 1, what is the median score? A) 70 B) 70.5 C) 71.5 D) 72

evablogger [386]

Answer:

B) 70.5

Step-by-step explanation:

Median = middle value when the values are placed in order.

If there are two middle values, the median is the mean of those two values.

<u>Class 1</u>

45 46 51 52 53 53 61 63 64 65 66 68 70 <u>70 71</u> 73 76 77 79 81 82 83 84 87 90 92 93 95

There are 28 values in Class 1.

Therefore, there are two middle values: 14th and 15th values

14th value = 70

15th value = 71

$\implies \textsf{Median}=\dfrac{70+71}{2}=70.5$

Determinet the x-intercept for 3x+2y=14

DerKrebs [107]

The x-intercept is for y = 0.

Put y = 0 to the equation of a line 3x + 2y = 14

$3x+2(0)=14\\\\3x=14\qqud\text{divide both sides by 3}\\\\\boxed{x=\dfrac{14}{3}\to\left(\dfrac{14}{3};\ 0\right)}$
