Answer:

All the above

Answer:

The probability you will get a head at least once is 50%.

Step-by-step explanation:

Since the question is asking about the probability you will get, we can assume we’re answering based on theoretical probability. This type of probability is based on logic.

A coin always has two sides, one with head and the other with tails. So we can easily represent this as half and half. 1/2 as a fraction. 0.5 as a decimal. 50% as a percent. This means that P(H) will be equal to any one of these as they are all the same. The same can be said for the probability that a head does not appear, in other words, a tail appears. The reason being that the probability is split evenly between the two. This will again mean that P(T) will equal to any one of those.

So, A = 50% and B = 50%. The probability you will get a head at least once is 50%.

Answer: Question 1 : x + 3 = 14 and x = 14 - 3

Question 2: y/5 = 60 and y = 60 x 5

Solve each eqaution

2x = 5 : answer : x = 5/2

y + 1.8 = 14.7 (subtract 1.8 on each side) : answer = 12.9

6 = 1/2z (combine terms) Answer 12

3 1/4 = 1/2 + W (Convert mixed numbers to improper fractions) answer = -1 9/13

2.5t = 10 : answer : 4

2.5t-(10)=0

t=10/2.5

(For 3 I can't draw the diagram asked. sorry)

21.2 - 0.82 = 20.38

2.05 x 0.004 = 0.00820.

Lin is right. Jada method 60 divided by 4 (1/4 of 60) which gives you 15. Andre method: 25/100 x 60 = 50.

Answer:

Centre is [tex](7,11)[/tex]

Radius is [tex]6[/tex]

Step-by-step explanation:

The general equation for a circle is written in the form [tex](x-a)^2+(y-b)^2=r^2[/tex] , where [tex](a,b)[/tex] is the centre of the circle, and [tex]r[/tex] is the radius.

For your circle, [tex](x-7)^2+(y-11)=36[/tex], we can compare it with the general equation to find the centre and radius.

[tex]-a = -7[/tex]

[tex]-b = -11[/tex]

[tex]r^2 = 36[/tex]

Therefore, [tex]a=7[/tex], [tex]b=11[/tex] and [tex]r=6[/tex].

Centre at [tex](a,b)[/tex] which is [tex](7,11)[/tex] .

Answer:

SSS (Side-Side-Side)

Step-by-step explanation:

It is given that PS ≅ RQ. Shown by congruency symbols, PR ≅ RQ. Lastly, QR ≅ QR due to the reflexive property.

Due to all three sides between the two triangles being congruent, you can conclude that they are congruent by SSS, or Side-Side-Side.

Answer:

-log(2)

Step-by-step explanation:

The circle is centered at (−2, 4) and has a radius of 15.

i took the test

A circle represented by the equation (x+2)² + (y - 4)²= 225 is centred at  (-2,4) and has a radius of 15.

The equation of a circle is represented as follows:

where

(h, k) = centre

r = radius

Therefore, (x+2)² + (y - 4)²= 225 has the following centre and radius.

Then

(h, k) = (-2,  4)

Therefore, the circle is centred at (-2,4) and has a radius of 15

Answer: C-26

Step-by-step explanation: First you need to figure out how many total cars he needs to sell through the year by multiplying 12 by 18. This should get you 216. Now, we need to add all of his actual stats that we have so far to get a total of 190 cars sold. We know he needs 216 total by the end of the year, so we just have to subtract 190 from 216 to get our answer, 26.

ANSWER :

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius.

Answer: 1.86 gallons

Step-by-step explanation:

A jet ski can go 50 miles using one gallon of gas. To find the number of gallons needed for 150 kilometers, first convert kilometers to miles:

1 mile = 1.60934 kilometers

150 kilometers will be:

= 150 / 1.60934

= 93.2059 miles

If a jet ski can go 50 miles on one gallon, the number of gallons required for the above is:

= 93.2059 / 50

= 1.86 gallons

Answer:

The answer is "The claim is plausible because 3 head movements per minute are contained within the interval".

Step-by-step explanation:

The wet-growing process of creation, located in western Florida, is researched by animal researchers. Food production is the process of finding food. The researchers had collected a sampling of 63 lizards with the number of head motions per minute to investigate such behavior. The sample-based confidence interval of 95% is given as hand gestures of 2.7±0.62 per minute. Depending on the interval, a statement of 3 hand gestures is plausible per minute then within the interval, there have been three head motions per minute.

Answer:

x = 4

y = 10

Step-by-step explanation:

3x + 2y = 32 (Multiply this equation by -3)

9x - 3y = 6

-9x - 6y = -96

9x - 3y = 6

-9y = -90

y = 10

3x + 2y = 32

3x + 2(10) = 32

3x + 20 = 32

3x = 32 - 20

3x = 12

x = 4
