Mathematics

Answer:

80°

Step-by-step explanation:

The reference angle is the smallest angle that the terminal side of a given angle makes with the x-axis.

An angle of -440° lies in the fourth quadrant.

For an angle θ in the fourth quadrant, the reference angle is 360° + θ.

The reference angle is

360° - 440° = 80°

It takes Carol 3 hours to drive from Ashdown to Bridgeton at an average speed of 50 mph.
Arada [10]
Answer= 59.8mph

So since it takes 3h of 50mph to get from Ashdown to Bridgetown Carol drives for 150miles. Because 3*50 is 150.
Then divide 60 by 70 which is 0.857. Then times 0.857 by 60 to see how long it took her , which is 51 mins. Add 3h and 51mins which gets you 3.51h.

Then add 150 and 60 to get 210. Divide 210 by 3.51 then you get 59.8 mph

I will brainlest this don't answer if out the real answe thank you
Mashutka [201]

Answer:

1) Product of 2 x 3/5 is 6/5 or 1 and 1/5.

2) 20/9 or 2 and 2/9

3) 15/8 or 1 and 7/8

4) 15/6 or 2 and 3/6 or 2 and 1/2

5) 6/4 or 1 and 2/4 or 1 and 1/2

Step-by-step explanation:

You multiply the whole number by the numerator (top number) and then divide the result by the denominator(bottom number). Afterward, simplify the fraction if you can, for example, 6/9. Both the numerator and denominator can be divided by 3. Therefore, the answer to that example is 2/3.

Which of the following represents a Type I error for the null and alternative hypotheses H0:μ≤$3,200 and Ha:μ&gt;$3,200, where μ
Nuetrik [128]

Answer:

Option a) Type I error would occur if we reject null hypothesis and conclude that the average amount is greater than $3,200 when in fact the average amount is $3,200 or less.        

Step-by-step explanation:

We are given the following information in the question:

H_{0}: \mu \leq \$3,200\\H_A: \mu > \$3,200

where μ is the average amount of money in a savings account for a person aged 30 to 40.

Type I error:

  • Type I error is also known as a “false positive” and is the error of rejecting a null  hypothesis when it is actually true.
  • In other words, this is the error of accepting an  alternative hypothesis when the results can be  attributed by null hypothesis.
  • A type I error occurs during the hypothesis testing process when a null hypothesis is rejected, even though it is correct and should not be rejected.

Thus, in the above hypothesis type  error will occur when we reject the null hypothesis even when it is true.

Option a) Type I error would occur if we reject null hypothesis and conclude that the average amount is greater than $3,200 when in fact the average amount is $3,200 or less.
