Find the least common multiple of 10 and 14.

aksik [14]

We can do this by just adding 14 to 14 until we get a number that is divisible by 10. We can do it this way because it will be a small number. Let's list them out. 14, 28, 42, 56, 70. 70 is divisible by 10, so 70 is the answer.

What is the equation in point-slope form of the line that passes through (-9, 12) with a slope of 5/6?

Hitman42 [59]

Answer:

$\large\boxed{y-12=\dfrac{5}{6}(x+9)}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point on a line

We have

$m=\dfrac{5}{6},\ (-9,\ 12)\to x_1=-9,\ y_1=12$

Substitute:

$y-12=\dfrac{5}{6}(x-(-9))\\\\y-12=\dfrac{5}{6}(x+9)$

The head of a computer science department is interested in estimating the proportion of students entering the department who wil

olya-2409 [2.1K]

Answer:

Step-by-step explanation:

From the given information:

At 95% Confidence interval level,Level of significance $\alpha$ 0.05, the value of Z from the standard normal tables = 1.96

Margin of Error = 0.10

Let assume that the estimated proportion = 0.5

therefore; the sample size n can be determined by using the formula: $n =(\dfrac{Z}{E})^2 \times p\times (1-p)$

$n =(\dfrac{1.96}{0.1})^2 \times 0.5\times (1-0.5)$

$n =(19.6)^2 \times 0.5\times (0.5)$

n = 96.04

n $\approx$ 96
