34kurt3 years ago
4 0

Step-by-step explanation:

Circumference of the circle= 30π units

2\pi \: r = 30\pi

r = 15 \: units

Area of the circle =

\pi {r}^{2}  = \pi {15}^{2}

= π225 sq. unit

=3.14× 225 sq. units

=706.5 sq units

Let a and b be the events of the fda approving and rejecting a new drug to treat hypertension, respectively. The events a and b
Law Incorporation [45]

The correct option is (d) Mutually exclusive events.

Let a and b be the events of the fda approving and rejecting a new drug to treat hypertension, respectively. The events a and b are mutually exclusive events.

Two events are mutually exclusive or disjoint in logic and probability theory if they cannot both occur at the same time. The results of a single coin toss, which can result in either heads or tails but not both, provide a clear illustration.

A statistical term used to describe events that cannot occur concurrently is "mutually exclusive." It is frequently used to refer to circumstances in which the occurrence of one event takes precedence over the other. For instance, it is impossible for war and peace to exist together. They are therefore opposed to one another.

PLEASE HELP! IM A MONTH BEHIND IN MATH AND FREAKING OUT T^T PLZZZZ
ANTONII [103]
A) Let x stand for time, y stand for velocity.
We are given the points (2,50), (6, 54). We can make a line using the slope intercept form
y = mx + b.
slope is (54 - 50)/(6-2)  = 4/4 = 1
y = 1x + b
plug in point (2,50) to find b
50 = 1(2) + b
50-2 = b
48 = b
the equation is  y = 1x + 48
Make standard form.
<span>x - y = -48
</span><span>b) make a table and plot points for the first 7 hours
Table Is attached.
Good Luck!

2. Solve the system using substitution. (1 point)
AveGali [126]

Answer:

(8, 11 )

Step-by-step explanation:

Given the 2 equations

2x + 2y = 38 → (1)

y = x + 3 → (2)

Substitute y = x + 3 into (1)

2x + 2(x + 3) = 38 ← distribute and simplify left side

2x + 2x + 6 = 38

4x + 6 = 38 ( subtract 6 from both sides )

4x = 32 ( divide both sides by 4 )

x = 8

Substitute x = 8 into (2) for corresponding value of y

y = 8 + 3 = 11

Solution is (8, 11 )

Which of the following expressions is equivalent to 4,325,000,000
Llana [10]

For this case we must find an expression equivalent to:

4,325,000,000

To express in scientific notation we must take into account that the power will be positive, that is, the decimal is run to the right.

We test each option.

Option A:

4,325 * 10^{-9}

If we run the decimal 9 spaces to the left we have:

0.000000004325

Option B:

We discard it because the exponent is negative.

Option C:

4,325 * 10 ^ 6

We run the decimal 6 spaces to the right

4,325,000

Option D:

4,325 * 10 ^ 9

We run the decimal 9 spaces to the right

4,325,000,000

Answer:

Option D
