9. Evaluate the ceiling function for the given value.
A. f(x) = ⌈x⌉; x = −7.4

B. g(x) = ceiling (x, 0.50);
x = 21.27

Answers

Given:

A. f(x) = ⌈x⌉; x = −7.4

B. g(x) = ceiling (x, 0.50); x = 21.27

To find:

The values of ceiling function for the given value.

Solution:

We have,

f(x) = ⌈x⌉; x = −7.4

Here, f(x) is a ceiling function, so we need to find the nearest next integer value because if m < x ≤ n, then ⌈x⌉ = n, where m and n are integers.

Now,

f(-7.4) = ⌈-7.4⌉

f(-7.4) = -7

Therefore, the value of f(x) is -7 at x=-7.4.

g(x) = ceiling (x, 0.50); x = 21.27

Here, g(x) is a ceiling function with 0.50, so we need to find the nearest next multiple of 0.50 because if m < x ≤ n, then ⌈x⌉ = n, where, m and n are multiples of 0.50.

Now,

g(21.27) = ceiling (21.27, 0.50)

g(21.27) = 21.50

Therefore, the value of g(x) is 21.50 at x=21.27.

Write the power of 10 to multiply the divisor by to make it a whole number. Then, write the equivalent problem and find the quotient.

16.65 divided by 0.37
i need halp wit this and also i brainly keeps deleting meh questions

Answers

Answer:

Step-by-step explanation:

The equivalent problem is 16.65×10²/0.37×10² and the quotient is 45.

What is a quotient?

In arithmetic, a quotient is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.

Given that, 16.65 divided by 0.37.

Now, multiply both numerator and denominator by 10², we get

16.65×10²/0.37×10²

= 1665/37

= 45

Therefore, the quotient is 45.

Answer: Lower left corner [tex]\frac{29}{18+29} \times 100[/tex]

We have 29 people who chose fishing out of 18+29 people who filled out the survey. We don't use 60 because not everyone filled out the survey, and we're only focusing on survey participants. The "times 100" at the end will move the decimal point 2 spots to the right, and convert it to percent form.

For example, if you had 2 people who liked fishing out of 8 total then 2/8 = 0.25 = 25% of the people like fishing.

Answer:it's C) 29×100/18+29

Step-by-step explanation:

For the percentage, we need the total number of boys who completed the survey which is 18+29. Again, the number of boys who chose fishing is 29. So, we should divide 29 by (18+29) & multiply 100c with it in order to get the percentage .
