Answer:
x is equal to 16
Step-by-step explanation:
Combine multiplied terms into a single fraction
Multiply by 1
Subtract 7 from both sides of the equation
Simplify it
Subtract 3 from both sides of the equation
Simplify
Multiply all terms by the same value to eliminate fraction denominators
Simplify
Subtract 2 from both sides of the equation
Simplify
Divide both sides of the equation by the same term
Simplify!
That's it!
The probability will be "0.7497".
Given:
Mean,
Standard deviation,
Number of babies,
The standard error of sample will be:
→
hence,
→ P(4 babies will be between 8.4 - 9.6 pounds)
Thus the above response is right.

Complete question:
Some sources report that the weights of full-term newborn babies in a certain town have a mean of 9 pounds and a standard deviation of 0.6 pounds and are normally distributed.
Answer: 0.7497
Step-by-step explanation:
Mean = 9
sd = 0.6
n = 4
P(4 babies will be between 8.4 and 9.6 pounds)
P(8.4 ≤ X ≤ 9.6)
Standard error of the sample (S. E) :
S. E = sd/√n
= 0.6 /√4
= 0.6/2
= 0.3
P(8.4 ≤ X ≤ 9.6)= ((P(8.4 - 9) / 0.3) ≤ X ≤ (9.6 - 9)/0.3)
P(8.4 ≤ X ≤ 9.6) = P(-2 ≤ X ≤ 2)
P(Z ≤ 2) - P(Z < - 2)
0.9772 - 0.2275 = 0.7497
Answer:
it would be 0.4 to the power (exponent) of 3

should the answer be 0.4^3
(hope this helps can i plz have brainlist :D hehe)
ex– 1 = 9
Answer:
x = ln 10
Step-by-step explanation:
You meant e^x - 1 = 9. Let's isolate e^x, by adding 1 to both sides. We get:
e^x = 10
Now make use of the property ln a = b <=> a = e^b
Then e^x = 10 becomes
x = ln 10
Answer:
24 crates
Step-by-step explanation:
The usable load capacity for 40-kg crates is ...
1050 kg - 82 kg = 968 kg
The number of 40-kg crates that can be loaded in a trailer with this capacity is ...
floor(968/40) = floor(24.2) = 24 . . . . crates
_____
The function floor(n) gives the greatest integer less than or equal to n. For positive numbers, it drops the fraction.
