Area of triangle = A = ?
<u>Formula:</u>
A = bh / 2
<u>Solution:</u>
A = (4)(4) / 2
A = 16 / 2
A = 8 cm²

Answer:
<h2>The slope m = -1</h2>
Step-by-step explanation:
Look at the picture.
The formula of a slope:
From the graph we have the points (-5, 2) and (-3, 0). Substitute:
First you would have to get them to have the same denomitator so 2 3/4 is the same as 2 6/8 but u cant subtract 1 by 6 so u move 1 8/8 over from 5 1/8 and get 4 9/8 and then u subtract and get 2 3/8
When an equality is set up like this you are going to have 2 answers
Original inequality: <span>-3 ≤ 5 – 2v < 7
</span><span>When you solve this problem, solve it by making two equations
You will reuse 5-2v in both equation
-3 </span>≤ 5-2v
&
5-2v < 7
now do simple math
-3 ≤ 5-2v
-8 ≤ -2v
4 ≤ v
however when you divide when you divide by a negative number for an inquality you MUST change the sign to its opposite so
4 ≤ v will be 4≥ v
5-2v < 7
-2v < 2
v < -1
since we divide by a negative in order to get the variable by itself we change the sign to its opposite
v < -1 becomes v > -1
The probability is about 85.29%.
To do this, you need to first find the z-score on each end of the interval. Then, you can subtract the percents to find the percent in the middle.
Lower:
(1000 - 1252) / 129 = -1.18 which gives a probability of 11.9%
Upper:
(1500 - 1252) / 129 = 1.92 which gives a probability of 97.19%
97.19 - 11.9 = 85.29
