Answer:
(3+2)×5= 5 power 2
5 power 3= 125
10 power 2 over 2= 50
Step-by-step explanation:
Answer:
the answer is acute 35.
Step-by-step explanation:
1. (0.5)2=1
2. (-0.2) + (-0.05) = -0.25
3. |-3 + 2.75| = 0.25
4. -(-0.25) = 0.25
5. 2x - 1.75x = 0.25x
So your answers are 3 and 4.
Answer:
28 + 8y - 8
Step-by-step explanation:
According to the problem;
-2(3x + 12y - 17x - 16y + 4)
Collecting like terms;
-2(3x -17x + 12y - 16y + 4)
-2(-14x - 4y + 4)
28 + 8y - 8
None of the options matches the correct answer.
Answer:
The probability is 0.683
Step-by-step explanation:
To calculate this, we shall be needing to calculate the z-scores of both temperatures
mathematically;
z-score = (x-mean)/SD
From the question mean = 78 and SD = 5
For 73
z-score = (73-78)/5 = -5/5 = -1
For 83
z-score = (83-78)/5 = 5/5 = 1
So the probability we want to calculate is within the following range of z-scores;
P(-1 <z <1 )
Mathematically, this is same as ;
P(z<1) - P(z<-1)
Using the normal distribution table;
P(-1<z<1) = 0.68269 which is approximately 0.683
