Answer:
15
Step-by-step explanation:
Let x be the number
3 times the number = 3x
7 more than 3 times a number = 3x +7
3x + 7 = 52
3x = 52 -7
3x = 45
x = 45/3
x = 15
Hello!
You put -2 in for x
I don't know whether it is times x or to the power of x so I will do both
5 * 3 * x
5 * 3 * -2 = -30
------------------------------------------------------------------------------------------------------
5 * 3^x
5 * 3^-2
5 * 1/81 = 5/9 or 0.55555
Hope this helps!
Answer:
The histogram is right-skewed.
Step-by-step explanation:
The income of all households in the United States can be categorized as low, medium and high.
Not many people earn a high income. So the proportions of people decreases as the income increases.
Most of the people earn a medium income. So the mode of the data would be somewhere in the start of the the distribution.
There are many households that earn a low income. But this proportion is not more than the proportion of people earning low income.
So the histogram for income distribution will have a long right tail with maximum data at the starting point.
This implies that the histogram is right-skewed.
Answer:
47.8°
Step-by-step explanation:
Let's first outline the important parameters
--- <V = 90°
Vt = 64
UV = 43
The angles in a triangle sums up to 180,but we don't have up to 2 angles given so as to find the third one. What we have to is to find the second angle,in this case T,using the sine rule.
Sin v/v = sin t/t
(Sin 90)/64 = sin t/43
Cross multiply and we have
43 sin 90 = 64 sin t
Sin t = 43 sin 90 ÷ 64
Sin t = 0.6719
Sine inverse of t = 42.2°(the second angle)
Angle U = 180 -( 90 + 42.2)
180 - 132.2
= 47.8°
160/32= 5
5*5= 25 mm
25 mm <em>is how many millimeters represents the kilometers.
