Hello,
The answer is "x=91".
Reason:
First write the equation:
3^4+2*5=
Now use PEMDAS:
E goes first:
3^4=3*3*3*3=81
81+2*5
M goes next:
2*5=10
81+10=
Now use A:
81+10=91
x=91
If you need anymore help feel free to ask me!
Hope this helps!

Answer:
The probability that the average length of rods in a randomly selected bundle of steel rods is greater than 259 cm is 0.65173.
Step-by-step explanation:
Step-by-step explanation:
We are given that a company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 259.2 cm and a standard deviation of 2.1 cm. For shipment, 17 steel rods are bundled together.
Let = the average length of rods in a randomly selected bundle of steel rods
The z-score probability distribution for the sample mean is given by;
Z = ~ N(0,1)
where, = population mean length of rods = 259.2 cm
= standard deviaton = 2.1 cm
n = sample of steel rods = 17
Now, the probability that the average length of rods in a randomly selected bundle of steel rods is greater than 259 cm is given by = P( > 259 cm)
P( > 259 cm) = P( > ) = P(Z > -0.39) = P(Z < 0.39)
= 0.65173
The above probability is calculated by looking at the value of x = 0.39 in the z table which has an area of 0.65173.
Answer:
1. 1/20
2. $16.32
Step-by-step explanation:
QUESTION 1:
Find the least common factor of 2, 5, and 4, which is 20.
1/2 is 10/20, 1/5 is 4/20, and 1/4 is 5/20.
10-4-5=1
1/20
QUESTION 2:
Multiply each number 32 times except for 80
44.8
18.88
Then add them together
63.68
Now subtract them from 80
16.32
50 over 360 * 7.2*pi = 3.14159...
