Estimate 3/4% of 168​

Mathematics
1 answer:
Anestetic [448]2 years ago
8 0

Answer:

120

Step-by-step explanation:

we can round 168 down to 160 because it is easily divisible by 4.

160/4 = 40 (which is about 1/4 of 168)

multiply by 3 to get 3/4 (1/4 x 3 = 3/4)

40 x 3

=120

What is the leading coefficient of the polynomial?
ANEK [815]

ANSWER

B) 15

EXPLANATION

The given polynomial is

23 {x}^{5}  + 12 {x}^{2}  + 19 { x }^{3}  + 15 {x}^{6}

We arrange this polynomial in ascending powers of x to obtain the standard form;

15 {x}^{6} + 23 {x}^{5}    + 19 { x }^{3} + 12 {x}^{2}

The degree of this polynomial is 6.

The coefficient of the leading term is 15

2-31 The following grade-point averages apply to a random sample of graduating seniors. 3.812.732.513.093.28 3.512.861.203.133.2
Dmitry_Shevchenko [17]

Answer:

The sample range is 2.61.

Step-by-step explanation:

We are given the following grade-point averages which apply to a random sample of graduating seniors below;

3.81, 2.73, 2.51, 3.09, 3.28, 3.51, 2.86, 1.20, 3.13, and 3.24.

As we know that the range of the data is calculated bu using the following formula;

               Range = Highest value in the data - Lowest value in the data

Here, Highest value = 3.81

          Lowest value = 1.20

So, the sample data range = 3.81 - 1.20

                                              = 2.61.

Which values of n degree polynomials must there definitely exist an x-intercept. Please explain all the reasoning
AveGali [126]

Answer: There must be definitely at most n value of x - intercept

Step-by-step explanation: If a polynomial has a value of n degree, then, there must be definitely at most n value of x - intercept.

For instance, The polynomial has a degree of 8, so there are at most 8 x-intercepts and at most 8–1 = 7 turning points.

Using linear function concepts, it is found that:

a) The initial value is of 3 and the rate of change is of 20.

b) The rate of change means that for <u>each hour, the cost increases by 3 Dhs</u>, while the initial value means that <u>a flat fee of 20 Dhs is paid</u>.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and also can be considered as the initial value.

In this problem, the function that gives the charge C for renting a bicycle for h hours is:

C(h) = 3h + 20

Item a:

Comparing to the standard function, we have that:

  • The initial value is of 3 and the rate of change is of 20.

Item b:

The rate of change means that for <u>each hour, the cost increases by 3 Dhs</u>, while the initial value means that <u>a flat fee of 20 Dhs is paid</u>.
