Step-by-step explanation:

f(x) = 4x + 1

g(x) = x² - 5

(f+g)(x) = f(x) + g(x)

= (4x + 1) + (x² - 5)

Below are 36 sorted ages of an acting award winner. Find Upper P70 using the method presented in the textbook.
Leona [35]
The upper 70th percentile is the number below which 70% of the data lie.

The 70th percentile position is given by:

P_{70}= \frac{70N}{100} = \frac{70(36)}{100} =25.2

Thus, the 70th percentile position is approximately the 25th data item (after the data has been arranged in acsending order).

Given the following data:
<span>16 24 25 26 27 29 36 39 39 39 40 44 45 47 47 48 50 51 51 53 53 54 57 58
58 60 65 66 67 69 69 71 72 74 74 74

The 25th data in the data set is 58.

Aloiza [94]

Answer:

1 cm to 7.5 m

Step-by-step explanation:

A drawing scale is a ratio of two numbers.

The given scale, 4 cm to 30 m, can be written as a ratio in the form of a fraction,

(4 cm)/(30 m)

Since it can be written as a fraction, it can also be reduced like a fraction.

The problem wants the number of cm to be 1 cm. We have 4 cm.

Divide the numerator and denominator by 4.

(1 cm)/(7.5 m)

Now write it in the format the problem asks.

1 cm to 7.5 m
