How do you solve (-5+(-1 3/4))

1 answer:

8 0

$\bf \left[-5+\left( -1\frac{3}{4} \right) \right]\implies \left[-5+\left( -\frac{1\cdot 4+3}{4} \right) \right]\implies \left[ -5+\left(- \cfrac{7}{4} \right) \right]
\\\\\\
-5-\cfrac{7}{4}\implies \cfrac{(4)(-5)~-~(1)(7)}{4}\implies \cfrac{-20-7}{4}\implies \cfrac{-27}{4}\implies -6\frac{3}{4}$

Three-fourths of a research team worked in a lab while one-fourth of the team worked near a pond. Of the researchers who worked

Lisa [10]

Answer:

3.5%

Step-by-step explanation:

In this case, the final probability would be the product of the two probabilities that the plating shows us:

First probability would be:

We are told that three quarters of the equipment (3/4) in the laboratory and the other quarter (1/4) near the pond, we are interested in the latter, that is, the probability is 1/4 = 0.25

Second probability:

We are told that 14% collected insects, therefore it would be 0.14

The final product is the question they ask us:

0.25 * 0.14 = 0.035

Which means that the joint probability is 3.5%

Marty is taking piano lessons. She is going to practice every afternoon. The 1st week she practiced for 11 minutes each day. The

Answer:

$m=7w+4$

Step-by-step explanation:

Linear Modeling

It consist is setting up a linear relationship between two variables, given some experimental data. Only 2 points are needed to set up the equation of a line, but if more than 2 points are used, then the result should use statistical approaches like linear regression to find the best-fit line.

For the question at hand, Marty practices his piano lessons 11 minutes the week #1. It provides the first point (1,11). He practices 25 minutes per day on the third week. It gives us another point (3,25). This is enough to find the equation of a line. The general formula for a line, having two points (m1,w1) (m2,w2) is

$\displaystyle m-m_1=\frac{m_2-m_1}{w_2-w_1}(w-w_1)$
