Answer:

100

Step-by-step explanation:

To make a perfect square trinomial, you want to divide the use the following equation to find the missing constant:

(\frac{b}{2} )^{2} when the quadratic is in standard form.

In this case, we would divide -20 by 2 and square it

-20/2 = -10

(-10)^2 = 100

(a - b)² = a² - 2ab + b²

- 2ab = 20x

- ab = 10x } => b = - 10

a = x

(x - 10)² = x² - 20x + 100

Hi. Please I need help with this :
ki77a [65]

Answer:

1.79553

Step-by-step explanation:

Step 1: Write expression

log₁₀(√(69.5² - 30.5²))

Step 2: Evaluate square root

log(√(4830.25 - 930.25))

log(√3900)

log(62.45)

Step 3: Find log

log₁₀ (or log)

log(62.45) = 1.79553

-------------------------------------

To use the table method. we find values that are easily evaluated by log₁₀

log₁₀(10) = 1

log₁₀(50) = 1.69897

log₁₀(100) = 2

So we know that log₁₀(62.45) is between 1 and 2 and greater that 1.69897.

HELPPPPP!!! The data shows the weights of babies, in ounces, born at a local hospital in the month of January. 112, 118, 120, 67
lorasvet [3.4K]

Answer:

6

Step-by-step explanation:

The outlier is 67.

The mean with the outlier is: 115

(112+ 118 + 120 +67 + 128 + 119 + 121 + 124 + 126) ÷ 9

The mean without he outlier is: 121

(112+ 118 + 120 + 128 + 119 + 121 + 124 + 126) ÷ 8

So, 121 - 115 = 6
