What is the probability of flipping a coin 2 times and getting 2 heads? ​

Answer:

B) 60

Step-by-step explanation:

Given:

Equation:

<A + <B = 180

2x + 60 = 180

2x = 180 - 60

2x = 120

x = 60

Answer: $56.20

Step-by-step explanation:

Both the tax and the tips will be based on the total cost:

Tip = 43.57 * 20%

= $8.71

Tax = 43.57 * 9%

= $3.92

Total = Cost + Tip + Tax

= 43.57 + 8.71 + 3.92

= $56.20

Answer:

x = 6

Step-by-step explanation:

The median is half the sum of the parallel bases , then

[tex]\frac{2x+4+10x-50}{2}[/tex] = 13 ( multiply both sides by 2 to clear the fraction )

12x - 46 = 26 ( add 46 to both sides )

12x = 72 ( divide both sides by 12 )

x = 6

Answer:

Option A

Step-by-step explanation:

Out of 12 contestants, the judges will select either 3 or 4 contestant.

Number of groups that can be formed when judges pick three contestants

[tex]^{12}C_3[/tex]

[tex]220[/tex]

Number of groups that can be formed when judges pick three contestants

[tex]^{12}C_4\\495[/tex]

Number of more  groups that can be formed if the judges  pick four instead of three

[tex]= 495-220 = 275[/tex]

Hence, option A is correct

Answer:

the amount saved by her for two jeans is $16

Step-by-step explanation:

Given that

Misty purchased two pairs of jeans that cost $24 each

But they were on sale for one third of the total price

We need to find out the amount save

So, the amount saved is

= $24 × 1 ÷ 3 ×2 jeans

= $16

Hence, the amount saved by her for two jeans is $16

Answer:

64 1/2

Step-by-step explanation:

6(1/4+5/2)-2

parethesis first 1/4 +5/2 make them the same denominator 1/4 + 10/4 = 11/4

then 6 or 6/1 time 11/4 = 66/4= 16 1/2 - 2 = 64 1/2 i havn't done fractions in awhile so im not a 100% certain

Answer:

To draw the graph of linear equation of the form

 y-a=m (x-b)

We will first write it in slope intercept form which is of the form

It will cut x axis and y axis at ,  respectively.

As Euclid postulate States that, Unique equation of line can be Determined by two points, So join these two points. And Infinite number of points lie on a line.

Graph B

Step-by-step explanation:

The graph that represents the equation y - 2 = 3(x - 1) is: B. Graph B.

y = mx + b is used to represent the equation of a line in slope-intercept form, where, m is the slope and b is the y-intercept of the line.

Given the equation, y - 2 = 3(x - 1), rewrite the equation in slope-intercept form:

y - 2 = 3x - 3

y = 3x - 3 + 2

y = 3x - 1

The slope (m) is 3 and the y-intercept (b) is -1. Thus, the graph that has a slope of 3 and a y-intercept as -1 is graph B.

Answer:

Step-by-step explanation:

Rhonda should continue taking samples of ducks until both samples have at least one of each type of duck.

A migratory site is a place where animals, especially birds, congregate during their seasonal migration.

Rhonda should keep collecting duck samples until both samples contain at least one of each type of duck.

Because neither Sample 1 nor Sample 2 contain at least one of each type of duck, Rhonda must collect additional samples until this criterion is met.

Rhonda would be incorrect to infer the average population of each type of duck in the pond based solely on the two existing samples because the samples are not representative of the entire population.

Thus, Rhonda should collect additional samples until both samples contain at least one of each type of duck, and then use all of the samples together to infer the population of each type of duck in the pond.

Answer:

Mrs. Lopez made 50 quarts of sweet tea

Step-by-step explanation:

A gallon and a quart are two of the five US standard volumes of measurement. In relation to litres, a quart is 946.352946 millilitres while a gallon is  3.7854118 litres.

The relationship between The gallon and The quarts is given as 4:1

This means that for every 4  quarts, there is 1 gallon.

Now, let us find the number of quarts in 12¹/₂ gallons as follows:

1 gallon = 4 quarts

∴ 12¹/₂ gallons = 12¹/₂ × 4 quarts

converting the mixed fraction to improper fraction and multiplying:

= ²⁵/₂ × ⁴/₁

[tex]= \frac{25 \times 4 }{2 \times 1} = \frac{100}{2} \\\\= 50\ quarts[/tex]

We can see that there are 5 CDs, each of radius 9 cm

Area occupied by 1 disc:

Area of a circle = πr²

Area of disc = π(9)²

Area of disc = 3.14 * 81 = 254 cm²

Area occupied by 5 discs:

Area occupied by 5 discs = Area occupied by 1 disc * 5

Area occupied by 5 discs = 254 * 5

Area occupied by 5 discs = 1270 cm²
