One of your peers claims that boys do better in math desses than girls Together you run two independent simple random samples and calculate the given
summary statistics of the boys and the gets for comparable math classes in Calculus, 15 boys had a mean percentage of 82 3 with standard deviation of
56 while 12 girls had a mean percentage of 812 with standard deviation of 6 7 Which of the following would be the most appropriate test for establishing
whether boys do better in math dasses than girls?
Two sample z test for means
Two sample t test for means
Two sample z test for proportions
One sample test for means

true

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
