Answer:

2:13

Step-by-step explanation:

To simplify the ratio 4:26, we find the greatest common divisor of 4 and 26, and then we divide 4 and 26 by the greatest common divisor.

The greatest common divisor that you can use to simplify 4:26 is 2. Which means the answer to ratio 4:26 simplified is 2:13.

A researcher wanted to determine whether certain accidents were uniformly distributed over the days of the week. The data show t
Cloud [144]

Answer:

Chi-square = 4.600

Degrees of freedom= 6

there is no evidence to reject hypothesis.

Step-by-step explanation:

H₀ : uniformly distributed

H₁: not uniformly distributed                            

Suppose some value of observed or expected frequency  

Observed frequency : 39 40 30 40 41 49 41     Total: 280

Expected frequency  :  40 40 40 40 40 40 40  Total: 280

Calculated the chi-square value

Chi-square = sigma {(O-E)^2/E}

= 0.025+0.000+2.500+0.000+0.025+2.025+0.025  

 4.600

Degrees of freedom=d f = n-1 = 7-1 = 6

Chi-square for 6 d.f at alpha = 0.05 is 12.59

Chi-square of calculated value < its critical value at alpha = 0.05, we see that there is no evidence to reject hypothesis.

The frequency of Sat is wrongly taken as 41 instead of 51

Write the equation in y=(your answer) y is the y axis in coordinate plane.
Vitek1552 [10]

Answer:

y = 4

Step-by-step explanation:

Given the equation of the line, y = 6, passing through point (3, 4):

By definition, parallel lines have the <u>same slope</u>.

The linear equation, y = 6 is a horizontal line with a zero slope. Therefore, the parallel line must also have the same slope = 0.

Plug the given values from the point (3, 4) into the slope-intercept form:

y = mx + b

where:  y = 4, m = 0, and x = 3. We need to solve for the y-intercept, b:

y = mx + b

4 = 0(3) + b

4 = 0 + b

4 = b  

Therefore, the y-intercept is (0, 4).

For horizontal lines, the y-coordinate = 4 stays the same, while having different x-coordinates.

Therefore, the equation that is parallel to y = 6 is y = 4.
