The best way is to use real examples for them, things that trigger an actual memory or even a visual aid! (:

The best way for me to learn word problems is to sit down and write out or draw exactly what the problem is saying, line by line.

"Charlie has 3 Dollars"
$ $ $
"He spends 2"
$ | $$->
"How many does he have left"
$

Now this kind of thinking is used from basic addition, all the way up to data structures, number and graph theory, differential equations, physics. It is so useful to draw out stuff (:
I'm in college and I still draw apples on trees to try and visualize stuff. Picture in your head and write it out, if it doesn't make sense, try and draw it a different way!(: You got this.

The slope of the line passing through the points (-1, 5) and (1, 6) is no slope 1/2 5/4

zloy xaker [14]

Answer:

1/2

Step-by-step explanation:

Here you utilize the formula of slope which is m = y2-y1/x2 -x1

(-1,5) (1,6)

(x1, y1) ( x2, y2)

m = ( 6-5)/ (1-(-1))

= 1/(1+1)

= 1/2

Answer:

Tommy earned $55

Step-by-step explanation:

Proportions

Tommy and Mark made $88 raking leaves for Mrs. Bopp. They were paid the same rate and Tommy raked for 5 hours while Mark raked for 3 hours.

The total time both raked is 5+3=8 hours. The rate Mrs. Bopp paid them was $88/8 = $11 per hour.

Tommy raked 5 hours, so he earned 5*$11 = $55

Tommy earned $55

What is the product?

Lerok [7]

You just have to multiply straight across. Multiply the numerators for the new numerator, and the denominators for the new denominator.
5*3=15
4*8=32
15/32 is the answer (b).

Last year, 50% of MNM, Inc. employees were female. It is believed that there has been a reduction in the percentage of females i

anygoal [31]

Answer:

We conclude that there has been a decrease in the percentage of females in the company from last year.

Step-by-step explanation:

We are given that Last year, 50% of MNM, Inc. employees were female. It is believed that there has been a reduction in the percentage of females in the company.

This year, in a random sample of 400 employees, 180 were female.

Let p = percentage of females in the company this year.

So, Null Hypothesis, $H_0$ : p $\geq$ 50% {means that there has not been a decrease in the percentage of females in the company from last year}

Alternate Hypothesis, $H_A$ : p < 50% {means that there has been a decrease in the percentage of females in the company from last year}

The test statistics that will be used here is One-sample z proportion statistics;

T.S. = $\frac{\hat p-p}{{\sqrt{\frac{\hat p(1-\hat p)}{n} } } } }$ ~ N(0,1)

where, $\hat p$ = proportion of female in a sample of 400 employees = $\frac{180}{400}$ = 0.45

n = sample of employees = 400

So, test statistics = $\frac{0.45-0.50}{{\sqrt{\frac{0.45(1-0.45)}{400} } } } }$

= -2.0101

The value of the test statistics is -2.0101.

Now at 5% significance level, the z table gives critical value of -1.6449 for left-tailed test. Since our test statistics is less than the critical value of z as -2.0101 < -1.6449, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region due to which we reject our null hypothesis.

Therefore, we conclude that there has been a decrease in the percentage of females in the company from last year.
