The mean score of the maths test is 70 with a standard deviation if 12. Calculate the z-score of a student who got 55 marks. Interpret the result.
Answer:
Z = -1.2 ( It is below the group mean), The sudent performed less than average.
Step-by-step explanation:
From the question,
Applying
Z = (x-μ)/σ........................ Equation 1
Where Z = z-score, x = observed score or raw score, μ = mean of the score, σ = standard deviation of the score
Given: x = 55 marks, μ = 70, σ = 12
Substitute these values into equation 1
Z = (55-70)/12
Z = -15/12
Z = -1.25
Hence the z- score is negative, meaning it is below the group mean, I.e the student who get 55 marks, performed less than average
At the grocery store, 1 pound of deli turkey costs $6.20. Bernice orders 0.75 pounds of deli turkey. How much will Bernice pay for her order before taxes?
Answer:
Hello!
Since 1 pound of deli turkey cost $6.20, 0.75 pound of turkey would cost $4.65. So it would be $1.55 per 0.25 pound of deli turkey. Hope this helps.

solve the equation x^2- 10x - 3 = 0 to the nearest tenth
Answer:
x=10.29, x=-0.29
Step-by-step explanation:
Given data
x^2- 10x - 3 = 0
a=1
b=-10
c=-3
substitute into the following expression we have
x=(-b±√(b²-4ac))/(2a)
x=(-(-10)±√((-10)²-4*1*-3))/(2*1)
x=10±√100+12))/(2)
x=10±√112))/(2)
x=10±10.58/(2)
x=10+10.58/(2) , x=10-10.58/(2)
x=20.58/(2) , x=-0.58/(2)
x=20.58/2, x=-0.58/2
x=10.29, x=-0.29

Answer:
Step-by-step explanation:
Step 2.
He added 25 as he was trying to complete the square. He should have added (-5/2)^2 to both sides.
Rule: you take the coefficient of the middle term, divide it by 2 and square the result. You are always going to get a positive result. Add this result to both sides.

Explain how to use a number line to find the sum 7 + −2.
Step-by-step explanation:
start at 7 on the number line. move to the left (because the value is negative) 2 jumps. you will land on 5.
Answer: 5
Step-by-step explanation:
Usually you would just do 7+-2 which is also 7-2 which equals 5 but since it's a number line you do this
You would locate 7 on the number line and do the same for -2
Once done, you would take the distance 2 is from 0 and push 7 there(basically moving it to 5) and that would be how you would use a number line to find the sum of 7 + -2
Now if the 2 was positive, this would be different and you would add the distance making it 9 but since it's negative you push it towards 0 which makes it 5
