23: 8-5×(-4)
24: 9+(-36)÷(-4)
Follow PEMDAS (parentheses exponents multiplication division addition subtraction)
23:
5×(-4)= -20
8-(-20) goes to 8+20.
8+20=28
24:
9+(-36)÷(-4)
-36÷(-4)=9
9+9=18
Bold is the answers.
Answer:
Yes, she is right.
in y = m*x + b
b is the initial value or the y-intercept.
If you know that a line has a slope of m <em>(was not given)</em> and a y-intercept of 7, what is the equation for that line in slope-intercept form?
y = m*x + 7
Answer:
0.4435
Step-by-step explanation:
Given that :
X is normally distributed:
mean(m) = 1,000
standard deviation (s) = 250
probability that X lies between 800 and 1,100?
Using the relation :
X = 800
Zscore = (x - m) / s
Zscore = (800 - 1000) / 250
Zscore = - 200 / 250
Zscore = - 0.8
P(Z ≤ - 0.8) = 0.2119
X = 1100
Zscore = (x - m) / s
Zscore = (1100 - 1000) / 250
Zscore = 100 / 250
Zscore = 0.4
P(Z ≤ 0.4) = 0.6554
P(Z ≤ 0.4) - P(Z ≤ - 0.8)
0.6554 - 0.2119
= 0.4435
Answer:
Step-by-step explanation:
LCD = 28
= 0.535 {Round off to tenth}
= 0.5
= 0.583 {Round off to tenth}
= 0.6
So 2/7 +1/4 is closer to 1/2
