Answer:
1420 bricks
Step-by-step explanation:
10 rows x 142 bricks in each row = 1420 bricks
Answer: the minimum score required for an A grade is 81
Step-by-step explanation:
Since the scores on the test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = scores on the test.
µ = mean score
σ = standard deviation
From the information given,
µ = 70.8
σ = 8.6
The probability value for the top 13% of the scores would be (1 - 13/100) = (1 - 0.13) = 0.87
Looking at the normal distribution table, the z score corresponding to the probability value is 1.13
Therefore,
1.13 = (x - 70.8)/8.6
Cross multiplying by 8.6, it becomes
1.13 × 8.6 = x - 70.8
9.718 = x - 70.8
x = 9.718 + 70.8
x = 81 to the nearest whole number
Hi there, so we know that all triangles add up to 180 degrees so we will take 38 and add it with 25 to get 63 then we subtract 180 by 63 to get 117 which is your awnser!! I mean I might be wrong but I’m probably right. I hope this helps!! Have a great morning, night, or day, Whatever it is for you!
If we let y be equal to zero, we get the roots of the equation. Because the equation is already in the factored form, we then say that the roots of the equation are x = 3 and x = 5. Another thing that is notable of this equation is that the graph would pass the x-axis at the points 3 and 5.
This is a quadratic equation because there are two roots and the highest exponent achievable by performing the expansion of the terms is 2. this equation can be of a parabola and the opening is upward because of the positive value of the numerical coefficients both of y and x in the opposite sides of the equation.
