Answer:
9
Step-by-step explanation:
Step 1:
2x - ( 5 - x ) = 13 + x Equation
Step 2:
2x - 5 + x = 13 + x Open the parenthises
Step 3:
3x - 5 = 13 + x Add
Step 4:
3x = 18 + x Add 5 on both sides
Step 5:
2x = 18 Subtract x on both sides
Step 6:
18 ÷ 2 Divide
Answer:
x = 9

Answer:
Step-by-step explanation:
Since the weight of the products are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = weight of the product.
µ = mean weight
σ = standard deviation
From the information given,
µ = 4 ounces
Variance = 0.25²
σ = √variance = √0.25² = 0.25
We want to find the probability that a randomly selected unit from a recently manufactured batch weighs no more than 3.5 ounces. It is expressed as
P(x ≤ 3.5)
For x = 3.5,
z = (3.5 - 4)/0.25 = - 2
Looking at the normal distribution table, the probability corresponding to the z score is 0.0228
Answer:
35 degrees
Step-by-step explanation:
line g d equals 180 degrees
180-145=35
because angle def and angle feg equals 180
Answer:
5,200
Step-by-step explanation:
Significant figure = digit number
they want you to change 5239 to 2 s.f
thus,5200 <--2 digit number
This is an exponential function.
The starting population is: 10,000 and it doubles every 14 years.
In 42 years ( 42 : 14 = 3 ) the population doubles 3 times.
The equation ( exponential ) is :
y = 10,000 * 2^n
In this case: n = 3
y = 10,000 * 2 ^3 = 10,000 * 8 = 80,000
Answer: In 42 years the population of this town will be 80,000.
