To solve for x, you need to isolate/get the variable "x" by itself in the inequality:
3x - 8 ≤ 23 Add 8 on both sides
3x - 8 + 8 ≤ 23 + 8
3x ≤ 31 Divide 3 on both sides to get "x" by itself
(x is any number less than or equal to 31/3)
-4x + 26 ≥ 6 Subtract 26 on both sides
-4x ≥ -20 Divide -4 on both sides [When you multiply/divide by a negative number to both sides of an inequality, you flip the sign </>]
(two negative signs cancel each other out and become positive)
x ≤ 5 (x is any number less than or equal to 5)
Answer: 252 is 84% of 300.
Step-by-step explanation: To find 84% of 300, first write 84% as a decimal by moving the decimal point two places to the left to get .84.
Next, the word "of" means multiply so we will multiply .84 × 300.
<h2>
(.84) (300) = 252</h2><h2>
</h2><h2>Therefore, 252 is 84% of 300.</h2>
Answer:
1.66
Step-by-step explanation:
We need to conduct a chi square test
The statistic used to check this is given by the below
∑(n, 1) = [(O(i) - E(i)] / E(i)
From the question, we're told the observed value is
Freshmen
Sophomore
Junior
Senior.
After that, we then calculate the expected value.
Freshman
0.3 * 300 = $90
Sophomore
0.24 * 300 = $72
Statistics then finally gives us this
X² = (93 - 90²)/90 + (68 - 72)²/72 + (85 - 78)/78 + (64 -60)²/60
X² = 3² / 90 + 4² / 73 + 13² / 78 + 4² / 60
X² = 0.1 + 0.212 + 2.167 + 0.266 x+
X² = 2.745
X = √2.745
X = 1.66
Answer:
24
Step-by-step explanation:
How do we know that a circle must complete up to 180, then we have to:
180 - 48 = 132
Now knowing this distance we can also know the other, starting from the same concept, in addition to what the circle below is like, a semicircle refers to so we divide by 2:
(180-132) / 2 = 24
Therefore the answer is 24.
We can also do it ABC is half of ADC. So ABC = 48/2 = 24
