Answer:
Correct option A: 0.6874
Step-by-step explanation:
Hello!
To calculate the area within the interval [-1.23; 0.83], you have to subtract to the probability accumulated till the lower value to the probability accumulated to the higher value, symbolically:
P(Z≤0.83)-P(Z≤-1.23)
You have to use the Z table to look for the corresponding values of probability. The negative value is in the left entry and the positive value is in the right entry. The first column shows the integer and first decimal value, the second decimal value is in the first row, you cross both values and find the value of probability.
P(Z≤0.83)-P(Z≤-1.23)= 0.7967 - 0.1093= 0.6874
I hope it helps!
LWH=V
increasse by 10% means times 1.10
increase by 20% is times 1.20
L turns to 1.1L
W turns to 1.1W
H turns to 1.2H
(1.1L)(1.1W)(1.2H)=1.452LWH
so it is increased by 45.2%
A. (x+8)^ 2 + 1
B. (x-3)^ 2 - 8
C. ( x - 3/2) ^ 2 - 1/4
45, 45, 90
45 *π/180 = π/4
90 *π/180 =π/2
45, 45, 90 is the same as π/4, π/4, π/2
Answer:
y = 4x + -3
Step-by-step explanation:
1. Write the formula for slope y = mx + b
2. Find a point anywhere on the graph and use rise over run. Find slope by counting how many times you rise up.
3. You rose 4. The variable m is for the slope of a line so fill in the number 4. y = 4x + b
4. The variable b represents the y intercept and the y intercept is where the line crosses over the y axis. So that would be -3
5. Fill in the variable b with -3
6. Finally you would have y = 4x + -3
Hope this is right and hope this helps in the future!
