In order for you to figure out the price of a single apple you would simply divide. For example, $3.90/3 equals 1.3 also $6.50/5 equals 1.3. This means that one individual apple costs $1.30
*(This / sign means divide BTW)

It has been hypothesized that allergies result from a lack of early childhood exposure to antigens. If this hypothesis were true
skad [1K]

Answer:

[a]. check attachment.

[b]. It can not be said that the difference is ascribed to chance as P-value = 0.001 which is less than <<0.05. That is  P-value = 0.001 <<0.05.

Step-by-step explanation:

Without mincing words let's dive straight into the solution to the question above.

[a]. The drawing showing the histogram of bacterial endotoxin levels is given in the attached picture.

KINDLY NOTE: The data is right-skewed.

[b].  ALLERGIC             MEAN        SE MEAN         STDEV           N

      FALSE                     1510             251                  1789            251

        TRUE                    530              109                 343               10

False - true = difference in a.

Hence, 80 = estimated difference.

For the difference, 95% CI = (434, 1527).

DF = 58, P-value = 0.001, and the T value = 3.59.

Therefore, It can not be said that the difference is ascribed to chance as P-value = 0.001 which is less than <<0.05. That is  P-value = 0.001 <<0.05.

What letter stays the same when reflected over the x-axis
valina [46]

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.p explanation:

Shalnov [3]

Answer:

7/8

Step-by-step explanation:

If Haley bought  3/8 pounds of mozzarella and 1/2 pound of parmesan cheese we can convert 1/2 to eighths.

1/2 converted to eighths would be 4/8

4/8 + 3/8 = 7/8

She bought 7/8 pounds of cheese.
