Use the distributive property to expand the following expression.
Levart [38]

Answer:

-12.8x - 20y + 8.4

Step-by-step explanation:

To do this you just multiply everything by negative 4

so we have 3.2x*-4 + 5y*-4 - 2.1*-4

This gives us

-12.8x - 20y + 8.4

The last term is positive because we multplied a negative by another negative

Semmy [17]

Answer:

Answer:

a).

The amount spent on school materials for each term of all ST201students

b).

a).

It is not a random sample. This looks like a convenience sampling and there is sampling bias. This sample is not representative of the entire population. Since it is not a random sample it is not appropriate to generalize the results to all students.

b).

The sample size is 80 which is greater than 30. It is large enough to assume normal distribution according to central limit theorem.

c).

mean: $617

z critical value at 95%: 1.96

standard error = σ/sqrt(n) =500/sqrt(80) = 55.9017

lower limit= mean-1.96*se = 617-1.96*55.9017=507.43

upper limit= mean+1.96*se = 617+1.96*55.9017=726.57

d).

The amount spent on school materials for each term for the 80 ST201students is $617. We are 95% confident that amount spent on school materials for each term of all ST201students falls in the interval ($507.43, $726.57).

Whats a line passing<br> through the<br> points (0, 0) and<br> (5,-7)?
Ipatiy [6.2K]

Answer:

y = -7/5x

Step-by-step explanation:

First, we need to use the two points to find the slope.

m = y₁ - y₂ / x₁ - x₂

m = -7 - 0 / 5 - 0

m = -7/5

Now we know that the slope is -7/5. Now we'll substitute the information we've gathered into the point-slope form equation to get an equation.

y - y₁ = m(x - x₁)

y - (-7) = -7/5(x - 5)

y + 7 = -7/5x + 7

y = -7/5x

Therefore, the equation of the line is y = -7/5x.
