5x - 9y = -13 -2x + 3y = 4

1 answer:

4 0

Can you explain more? if your looking for the slope of both it is 5/9 for the fist one and 2/3 for the second. If your looking for y and x -intercept for the first one x intercepts at (-2,0) and y intercepts at (0, 4/3) and, for the second one x intercepts at ( -13/5, 0) and y intercepts at (0, 13/9)

2 divided by 2/5 I may ask to show ur work

pashok25 [27]

1. I would first write it out as fraction
2/1 divided by 2/5

2. When dividing fractions you need to find the reciprocal (opposite of or switched) of the fraction then multiply the two fractions together
2/1 divided by 5/2 <------- that's the reciprocal of 2/5

3. Now multiply

2 5 10
- x - = - = 5

4. 5 is your answer! :)

A gambler claims that horses in a horse race that start closer to the rail have an advantage over horses that start further from

k0ka [10]

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

4:3 19:11 equivalent ratios?

maria [59]

Answer:

Step-by-step explanation:

We can tell if these ratios are equivalent by dividing the numerators and denominators. If we end up with the same result, these ratios are equivalent.

 $\frac{4}{3}$   $\frac{19}{11}$ 

 $19 \div 4 = 4.75\\\\11\div 3 = 3.\overline{66}$ 

These two numbers are not equivalent, so these ratios aren't equivalent to each other

Hope this helped!
