Answer:

The weight of each large box = 18.25 kgs

The weight of each small box = 13.25 kgs

Step-by-step explanation:

Lets L = weight of large box and S = weight of small box

2L + 6S = 116

5L + 3S = 131

Multiply equation 5L + 3S = 131 by (-2)

-10L - 6S = -262

So now you have 2 equations

2L + 6S = 116

-10L - 6S = -262

---------------------------Add to eliminate S

-8L = - 146

L = 18.25

2(18.25) + 6S = 116

36.5 + 6S = 116

6S = 79.5

S = 13.25

Answer:

a) Null and alternative hypothesis:

$H_0: \pi=0.1\\\\H_a:\pi>0.1$

b) A Type I error is made when a true null hypothesis is rejected. In this case, it would mean a conclusion that the proportion is significantly bigger than 10%, when in fact it is not.

c) The consequences would be that they would be more optimistic than they should about the result of the investment, expecting a proportion of students that is bigger than the true population proportion.

d) A Type II error is made when a false null hypothesis is failed to be rejected. This would mean that, although the proportion is significantly bigger than 10%, there is no enough evidence and it is concluded erroneously that the proportion is not significantly bigger than 10%

e) The consequences would be that the investment may not be made, even when the results would have been more positive than expected from the conclusion of the hypothesis test.

Step-by-step explanation:

a) The hypothesis should be carried to test if the proportion of students that would eat there at least once a week is significantly higher than 10%.

Then, the alternative or spectulative hypothesis will state this claim: that the population proportion is significantly bigger than 10%.

On the contrary, the null hypothesis will state that this proportion is not significantly higher than 10%.

This can be written as:

$H_0: \pi=0.1\\\\H_a:\pi>0.1$

What is the slope of the line shown in the graph? A 3/2 B) 2/3 C) -3/4 D) -2/3

garik1379 [7]

Answer:

Step-by-step explanation:

y-intercept is (0, 3)

x-intercept is (4.5, 0)

formula to find the slope from two points is

$slope = m = \frac{y2 - y1}{x2 - x1} = \frac{y1 - y2}{x1 - x2} \\$

then the slope of the line that crosses (0, 3) & (4.5, 0) is

$m = \frac{3 - 0}{0 - 4.5} = \frac{3}{ - 4.5} = - \frac{3}{ \frac{9}{2} } = - \frac{2}{3}$

Divide R300 000 between Leona and Janet in the ratio 3:2.

ella [17]

Answer:

let the ratio be in x 

a/q. 3x + 2x = 300000

 5x = 300000

x = 300000/5

x= 60000

Leona = 60000*3 = 180000

Janet = 60000*2 = 120000

hope it helps

The infant mortality rate is deﬁned as the number of infant deaths per 1,000 live births. This rate is often used as an indicato

Basile [38]

(a)

Q1, the first quartile, 25th percentile, is greater than or equal to 1/4 of the points. It's in the first bar so we can estimate Q1=5. In reality the bar includes values from 0 to 9 or 10 (not clear which) and has around 37% of the points so we might estimate Q1 a bit higher as it's 2/3 of the points, say Q1=7.

The median is bigger than half the points. First bar is 37%, next is 22%, so its about halfway in the second bar, median=15

Third bar is 11%, so 70% so far. Four bar is 5%, so we're at the right end of the fourth bar for Q3, the third quartile, 75th percentile, say Q3=40

When the data is heavily skewed left like it is here, the median tends to be lower than the mean. The 5% of the data from 80 to 120 averages around 100 so adds 5 to the mean, and 8% of the data from the 60 to 80 adds another 5.6, 15% of the data from 40 to 60 adds about 7.5, plus the rest, so the mean is gonna be way bigger than the median of around 15.
