Answer:

0.9968

Step-by-step explanation:

Given that:

P of being correct = 0.5 (since there are only 2 options in each question with only one bring correct).

1 - p = 1 - 0.5 = 0.5

Number of questions, n = 12

Probability that atleast 2 questions are correct

P(x ≥ 2) = p(x = 2) + p(x = 3) +... + p(x = 12)

P(x =x) = nCx * p^x * (1 - p)^(n - x)

The sun of the individual probabilities gives us the answer or we could use the binomial probability calculator :

Hence,

P(x ≥ 2) = 0.9968

Answer:

16/3 or 5.3333.. in decimal

Step-by-step explanation:

Divide 80 and 15 by 5

16/3

Step-by-step explanation:

Sum of angles in a quadrilateral = 360°

Sum of first 3 angles = 360° - 100° = 260°.

260° / (4 + 6 + 3) = 20°.

First angle = (20°) * 4 = 80°

Second angle = (20°) * 6 = 120°

Third angle = (20°) * 3 = 60°

The angles are 80°, 120° and 60°.

Answer:

Let the angles of the quadrilateral be 4x, 6x, and 3x

Sum of the interior angles of a quadrilateral is 360°.

According to the above problem,

[tex]4x + 6x + 3x + 100 = 360 \\ 13x = 360 - 100 \\ 13x = 260 \\ \boxed{x = 20}[/tex]

Hence, the other three angles are 80°, 120° and 60°.

Answer:

20 % of n would be 12.8

Step-by-step explanation:

By first finding that 24.32 is 38% of 64. To find that you would have the fractions 38/100 = 24.32/n. From there you cross multiply the 100 times 24.32 then divide that answer by 38 to get the answer 64. you take that n=64 and find 20% of that which is 12.8.

The 20% of n is 12.8

38% of number n is given as:

[tex]38\% \times n = 24.32[/tex]

Express the percentage (38%) as decimal

[tex]0.38 \times n = 24.32[/tex]

Divide both sides of the equation by 0.38

[tex]n = 64[/tex]

Multiply both sides of the equation by 20%

[tex]20\% \times n = 20\% \times 64[/tex]

Express the percentage (20%) as decimal

[tex]20\% \times n = 0.20 \times 64[/tex]

Evaluate the product

[tex]20\% \times n = 12.8[/tex]

Hence, the 20% of n is 12.8

Answer:

100 years

Step-by-step explanation:

Simple interest means 4% on the 20$ only and forever.

100-20=80 dollars.

4% of 20 is 0.80

80/0.80 = 100

It will take 100 years

Answer:

It takes 41 years for $20 to grow to $99.86 and if you rounded that up, it would be $100 or if you want it to surpass $100 it would take 42 years turning $20 to $103.85

Answer:

11.52 miles

Step-by-step explanation:

We know that the length of an arc L = Ф/360 × 2πR where Ф = angle subtended by arc and R = radius of circle.

Now since Ф = 10 minutes = 10 × 1 minute = 10 × (1/60)° = (1/6)° and R = radius of earth = 3960 miles

So  L = Ф/360 × 2πR

= (1/6)°/360 × 2π(3960 miles)

= 1/2160 × 7920π

= 3.67π

= 11.52 miles

Answer:

The answer to the question provided is y = -3x - 12.

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ☟

[tex]y = mx + b[/tex]

❃Incase you also forgot, what the slope formula is ☟

[tex]m = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]

➊ First: We are going to be solving for the slope.

[tex]m = \frac{ - 9 - 6}{ - 1 - ( - 6)} = \frac{ - 15}{ \: \: \: 5} = - 3[/tex]

➋Second: We find the y-intercept.

[tex]y = mx + b \\ 6 = - 3( - 6) + b \\ 6 = 18 + b \\ \frac{ - 18 = - 18 \: \: \: \: \: \: \: \: \: \: \: \: }{ - 12 = b}[/tex]

Step-by-step explanation:

When rounding to the nearest ten, like I did with 524 above, we use the following rules:

A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.

B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.

C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.

The number of days to repair 8 km of road is given by the equation A = 32 days

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the number of days to repair 8 km be represented as A

Now , the proportion will be

Let the distance be = 1250 meters = 1.250 km

The number of days to repair 1.250 km is = 5 days

Substituting the values in the equation , we get

5 / 1.250 = A / 8

Multiply by 8 on both sides of the equation , we get

A = ( 8 x 5 ) / 1.25

A = 40 / 1.25

A = 32 days

Hence , the number of days is 32 days

Answer:

The image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:

Step-by-step explanation:

Given the point

(7, -7)

Translation of 3 right and 1 down means we need to add 3 units to the x-coordinate and subtract 1 unit from the y-coordinate

Therefore, the translation rule:

(x, y) → (x+3, y-1)

In our case, let the point P(7, -7)

P(7, -7)  → P'(7+3, -7-1) → P'(10, -8)

FOLLOWED BY A reflection over the x-axis

We know that the rule of reflection over the x-axis implies that

(x y) → (x, -y)

i.e. the x-coordinate of the point remains the same, but the y-coordinate changes its sign.

After the first transformation, we had got P'(10, -8)

so

P'(10, -8) → P''(10, -(-8)) → P''(10, 8)

Therefore, the image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:

We can pack a maximum of 15 blankets into the 22-inch moving box.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To determine how many blankets can fit in a 22-inch moving box, we first need to calculate the volume of the box.

Since the box is 22 inches in all three dimensions (length, width, and height), its volume is:

= 22 x 22 x 22

= 10,648 cubic inches

Next, we need to divide the volume of the box by the volume of one blanket to find out how many blankets can fit inside.

= 10,648 / 704

= 15.125

We can't fit a fraction of a blanket, so we can only pack a whole number of blankets.

Therefore,

We can pack a maximum of 15 blankets into the 22-inch moving box.
