Answer:
Step-by-step explanation:
Since the results for the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test reults
µ = mean score
σ = standard deviation
From the information given,
µ = 1700 points
σ = 75 points
We want to the probability that a student will score more than 1700 points. This is expressed as
P(x > 1700) = 1 - P(x ≤ 1700)
For x = 1700,
z = (1700 - 1700)/75 = 0/75 = 0
Looking at the normal distribution table, the probability corresponding to the z score is 0.5
P(x > 1700) = 1 - 0.5 = 0.5
Answer:
option A
12m/s
Step-by-step explanation:
Given in the question,
mass of object = 11kg
kinetic energy possess by = 792 joules
To find the velocity we use formula
v = 
Plug values in the formula
v = 
v = 
v = 
v= 12 m/s

Answer:
180
Step-by-step explanation:
cAN i have brainliest
So 8:1 or 9 parts total (8+1=9)
so ginger ale=8/9 of 12 or 8/9 times 12=96/9=32/3=10 and 2/3 oz
syrup=1/9, 1/9 times 12=12/9=4/3=1 and 1/3 oz
