Answer:

Step-by-step explanation:

If these two shapes are similar, then ratios of corresponding sides will stay constant. Therefore:

$\dfrac{g}{45}=\dfrac{50}{75}$

Multiply both sides by 45:

$g=\dfrac{50\cdot 45}{75}=30$

A maple syrup producer has a booth at a Sunday farmer's market. The producer sells organic maple syrup by the pint. To get custo

Answer:

See Explanation

Step-by-step explanation:

Given

$Price = 29.50 + 13.50(p - 2)$

The question has missing details. However, I will solve on a general term.

A possible question could be to find the cost of purchasing (say 10 bottles).

To do this, we simply substitute 10 for p.

So:

$Price = 29.50 + 13.50(p - 2)$

$Price = 29.50 + 13.50(10 - 2)$

$Price = 29.50 + 13.50 * 8$

$Price = 29.50 + 108$

$Price = 137.50$

i.e. $137.50 for 10 pint bottles

Another possible question is to calculate the number of pint bottles that amount to (say $70).

To do this, we simply substitute 70 for Price.

So:

$Price = 29.50 + 13.50(p - 2)$

$70 = 29.50 + 13.50(p - 2)$

Collect like terms

$70 - 29.50 = 13.50(p - 2)$

$40.5= 13.50(p - 2)$

Divide both sides by 13.50

$3= p - 2$

Add 2 to both sides

$3 + 2 = p - 2 + 2$

$5 = p$

$p = 5$

i.e. $70 will buy 5 pint bottles

Find the equation of the line that passes through (−4, 8) with slope −3. Write in slope-intercept form. F y = – 3x – 4 G y = – 4

storchak [24]

Answer: y=-3x-4

Step-by-step explanation:

Since we know slope, we can plug it into slope-intercept form to find the y-intercept by using the given points,

y=-3x+b

8=-3(-4)+b

8=12+b

b=-4

Now that we know the y-intercept, we can complete the slope-intercept form.

y=-3x-4

Answer:

Hence, the p-value ( 0.699986) > 0.05, FAIL TO REJECT THE NULL HYPOTHESIS

there is no significant evidence that starting position is a factor in horse races

Step-by-step explanation:

Given the data in the question;

Starting position: 1 2 3 4 5 6

# of Winners: 25 22 18 19 21 15

Mean x" (E) = (25+22+18+19+21+15)/6 = 120/6 = 20

Observed/Expected value table;

O E ((O-E)²) / E

25 20 1.25

22 20 0.2

18 20 0.2

19 20 0.05

21 20 0.05

15 20 1.25

∑ 3

so using chi square = ∑(((O-E)²) / E) = 3

DF = n-1 = 6-1 = 5

then, the critical chi square value is;

significance level = 0.05

chi square( critical ) = 11.07049769

from table;

p - value = 0.699986

Hence, the p-value ( 0.699986) > 0.05, FAIL TO REJECT THE NULL HYPOTHESIS

there is no significant evidence that starting position is a factor in horse races
