I believe it is 2c^8, but I'm not sure.
Y = -4x + -3
sorry if i’m wrong
To answer this problem we have to have a <span>Standard Normal Distribution table because we need to look up z scores. Then we use this equation
</span><span>z = (value - mean)/(standard deviation) = (250-200)/20 = 2.5.
</span><span>
The z score is then 2.5 </span>If so, look up z=2.5 on the left edge then you then determine from the table what the area to the left of that is.
<span>
Here are the conditions:
</span><span>p(z>2.5)=1
p(z<2.5)=.621
1-.621= .379
100-37.9= 62.1</span><span>
Given that, we should go with </span><span>.621%.</span>
Answer:
x = -48
Step-by-step explanation:
3/8 x - 6 = -24
Add 6 to each side
3/8 x - 6+6 = -24+6
3/8 x = -18
Multiply each side by 8/3 to isolate x
8/3 * 3/8x = 8/3 *-18
x = -48
Let check
3/8 (-48) -6 = -24
-18 - 6 = -24
-24=-24
This checks so this is the solution
Answer:
6
Step-by-step explanation:
Given that the coordinate plane, three of the vertices of the rectangle are located at (-1.25, -0.25),
(-1.25, 0.25), and (1.25, 0.25)
The length L of the shape will be:
L = 0.25 - ( - 0.25 )
L = 0.25 + 0.25
L = 0.5
The width of the shape will be:
W = 1.25 - ( - 1.25)
W = 1.25 + 1.25
W = 2.5
Perimeter P = 2L + 2W
Substitute the Length and the width into the formula
P = 2(0.5) + 2(2.5)
P = 1 + 5
P = 6 metres
Therefore, the perimeter of the shape is 6 metres
