Question 23 of 25 What is the probability of flipping a coin 85 times and getting tails 30 times or fewer? Round your answer to the nearest tenth of a percent. A. 99.8% B. 33.2% C. 0.4% D. 95.9%​

Answer:

341 cm²

Step-by-step explanation:

The base is 11 x 11 = 121

Then there is 4 side that are triangles, 11 x 10 ÷ 2 = 55 ----->  55 x 4 = 220

220 + 121 = 341

Answer: He bought 1 magazine and 3 comic books.

Step-by-step explanation: If comic books cost $1 and magazines cost $3, the equation for the problem should look like this: 2(m) + 1(c) = 5, since you know that the brother spent $5 in total. "m" represents the number of magazines purchased while "c" represents the number of comic books purchased. If you plug in 1 for "m" and 3 for "c", the equation would be true and would equal a total of $5. Also, 1 magazine and 3 comic books would mean that the little brother did, in fact, purchase 4 items.

Where the above parameters are given,  Shamika's total after the discount is $56.25. (Option D)

According to the table, if the total purchases are less than $50, the discount is 25%.

Shamika bought 3 skirts at $25 each, so her total purchase amount is 3 * $25 = $75.

Since $75 is less than $50, she qualifies for a 25% discount.

To calculate the discount, we multiply the total purchase amount by the discount rate  -

Discount = 25% of $75 = (25/100) * $75 = $18.75

To find her total after the discount, we subtract the discount from the total purchase amount  -

Total after discount = Total purchase amount - Discount

Total after discount = $75 - $18.75 = $56.25

Therefore, Shamika's total after the discount is $56.25. (Option D)

Answer:

Step-by-step explanation:

Expression evaluated by the student is,

(-4 + x)

For x = [tex]-9\frac{1}{2}[/tex]

Value of the expression will be,

(-4 + x) = [tex]-4+(-9\frac{1}{2})[/tex]

           = [tex]-4-9-\frac{1}{2}[/tex]

           = [tex]-13-\frac{1}{2}[/tex]

           = [tex]-13\frac{1}{2}[/tex]

While student evaluated the value of the expression as [tex]-5\frac{1}{2}[/tex].

Mistake done by the student may be in the first step [tex][-4+(-9\frac{1}{2})][/tex].

He might have subtracted [tex](-9\frac{1}{2})[/tex] from (-4).

The area of this triangle is.. [tex]30 in^2[/tex]

Step-by-step explanation:

6 x 10 divided by 2 = 30

Answer:

30 cm²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 6 and h = 10 , then

A = [tex]\frac{1}{2}[/tex] × 6 × 10 = 3 × 10 = 30 cm²

Answer:

$28.05

Step-by-step explanation:

If you want to find how much the photo album is after the markup, you first have to find 10% of the original price. 10% of $25.50 is $2.55, so you add $2.55 and $25.50 to find the price after the markup.

Answer:

t ≤ 10

Step-by-step explanation:

To solve the inequality, simplify it.

-3t + 9 ≥ -21

Subtract 9 from both sides.

-3t ≥ -30

Divide by -3. When dividing by a negative, flip the inequality sign.

The answer is C, t ≤ 10.

Answer:

C) 40

Step-by-step explanation:

For every one day your work is 5 hours.

1 day = 5 hours

Set up a proportion so it would be:

[tex]\frac{1 day}{5 hours} = \frac{4 days}{x hours}[/tex]

4 days x 5 hours = 20 hours/week

So now you know you know you work 20 hours/week, then multiply by 2 since they're asking how many hours will you work in two weeks:

20 hours x 2 weeks = 40 hours in two weeks

Answer:

R(x, y) = (x, -y)

Step-by-step explanation:

When we have a reflection across some line, the distance between the original point and the reflected point to the line is invariant.

For a reflection around the x-axis, the x-value is invariant, then the only value that can change is the y-value.

So if we have a point like (4, 7)

Which is at a distance of 7 units to the x-axis, the only other point that is also at a distance of 7 units to the x-axis that has the same x-value is (4, -7)

Here we already can see the rule.

If we have a point (x, y), the reflection across the x-axis gives us the point (x. -y)

Then we can write this reflection as a function in the next way:

R(x, y) = (x, -y)

This means that if the input is the point (x, y), the output is the point (x, -y)
