He can fill 7 glasses because 1/4 can go into 3/4, three times and 1/4 can go into 1, four times ( 1 is the same as 4/4) then add 3+4 which equals 7.
Step-by-step explanation:
Since y = (x + 3)(x + 3), the root is x = -3.
Only Graph A touches the x-axis once.

Answer:
x=175/3
Step-by-step explanation:
700/1200=x/100
Simplify to 7/12
7/12=x/100
Multiply both sides by 100
7/12×100=x
Simplify 7/12 ×100 to 700/12
700/12=x
Simplify 700/12 to 175/3
175/3=x
Switch Sides x=175/3
hope that helps you
Answer:
Step-by-step explanation:
Since the scores of the math test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = math test scores.
µ = mean score
σ = standard deviation
From the information given,
µ = 76
σ = 5
The probability that a student scored below 65 is expressed as
P(x < 65)
For x = 65
z = (65 - 76)/5 = - 2.2
Looking at the normal distribution table, the probability corresponding to the z score is 0.014
The percentage of students that scored below 65 is
0.014 × 100 = 1.4%
