Answer:

4900

Step-by-step explanation:

When rounding a number such as 4928 to the nearest hundred, we use the following rules:

A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

In this case, Rule B applies and 4928 rounded to the nearest hundred is:

4900

What is the vertex of the function?

egoroff_w [7]

<h2>Explanation:</h2><h2></h2>

Here you haven't provided any function, so I'll assume this one:

$f(x)=3x^2-18x+33$

This is a quadratic function whose graph represents a parabola. Any parabola has its vertex at the point:

$V(x,y) \\ \\ \\ x=-\frac{b}{2a} \\ \\ y=f(-\frac{b}{2a}) \\ \\ \\ where: \\ \\ \\ f(x)=ax^2+bx+c \\ \\ \\ So: \\ \\ a=3 \\ \\ b=-18 \\ \\ c=33$

Therefore:

$x=-\frac{(-18)}{2(3)}=3 \\ \\ f(3)=3(3)^2-18(3)+33=27-54+33=6$

Therefore, the vertex is:

$\boxed{V(3,6)}$

Find X. <br> pls & thank you :)

Answer:

<u>The correct answer is D. 69</u>

Step-by-step explanation:

Let's recall that if an exterior angle has its vertex where two rays share an endpoint outside a circle, the measure of that exterior angle is found by dividing the difference between the measures of the intercepted arcs by two.

Therefore, we have:

x = (Measure of arch CD - Measure of arch BD)/2

Replacing with the real values:

x = (210 - 72)/2

x = 138/2 = 69°

<u>The correct answer is D. 69</u>

During a recent year, charitable contributions in the United States totaled $330 billion. The following graph shows to whom this

victus00 [196]

Answer:

$49,500,000,000 billion or $49.5 billion

Step-by-step explanation:

10% of 330,000,000,000 = 33,000,000,000

5% of 330,000,000,000 = 16,500,000,000

15% of 330,000,000,000 = 49,500,000,000

A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly. When first noticed, t

matrenka [14]

Answer:

509.35 feet

Step-by-step explanation:

16°23' means 16 degrees and 23 minutes. A minute is 1/60 of a degree.

16°23' = 16 + (23/60) = 16.383°

Similarly:

49°29' = 49 + (29/60) = 49.483°

When the boat is first noticed:

tan(16.383°) = 200 / a

a = 200 / tan(16.383°)

a = 680.27

When the boat stops:

tan(49.483°) = 200 / b

b = 200 / tan(49.483°)

b = 170.92

So the difference is:

a − b = 680.27 − 170.92 = 509.35

The boat traveled 509.35 feet from the time it was first noticed to the time it stopped.

In a study of variation in systolic blood pressure upon application of leaches, it is found that the standard deviation of the 2

kondor19780726 [428]

Answer:

Test statistic is [(n - 1) *S^2 ]/ σ ^2 = [(22 - 1) *(3.9)^2 ]/ (3.4) ^2

with 21 degrees of freedom

Yes this data fits at the 10% level of significance, so I would not reject that statistic of 3.9 mmHg as a wrong standard deviation

Step-by-step explanation:

use the expression I attached in the image to find

[(n - 1) *S^2 ]/ σ ^2

where S = the standard deviation calculated from the sample of n trials.

sigma is the population standard deviation.

[(22 - 1) *(3.9)^2 ]/ (3.4) ^2 = 21 * 15.21 / 11.56 = 27.6306

all we have to do now is to make sure this number is in the 90 % confidence

interval. remember this has 21 degrees of freedom, look at the chi-squared chart.

11.5913 < 27.6306 < 32.67905

where 11.5913 is the lower bound of the chart

and 32.67905 is the upper bound
