62 people like coffee or tea, or both

A survey of 70 people found that 50 like coffee, 25 like tea, and 13 like both.

The amount of people that like only coffee = 50 - 13 = 37

The amount of people that like only tea = 25 - 13 = 12

The amount of people that like neither = 70 - (37 + 12 + 13) = 8

The amount of people who like coffee or tea, or both = 37 + 12 + 13 = 62

Answer:

13 like both

12 like tea

37 like coffee

62 people like coffee, tea or both

8 don't like neither of them

Step-by-step explanation:

let us remember that 25 people like tea but 13 of them like both. And 50 people like coffee but 13 like both.

so:

25-13=12

12 equals to the number of people that only like tea.

50-13=37

37 equals to the number of people that only like coffee.

If you add the 13 (that like both) + 12 (that like tea) + 37 (that like coffee) that equals to 62 people that like coffee or tea, or both.

13+12+37=62

62 equals to the number of people that like coffee or tea, or both

So that means that 8 people don't like either coffee or tea.

Step-by-step explanation:

Answer:

2.203

Step-by-step explanation:

Subtract 7/10 from both sides of the equation

2.903 = [tex]y[/tex] + 7/10

2.903 - 7/10 = y + 7/10 - 7/10

Subtract the numbers

2.903 - 7/10 = y + 7/10 -7/10

2.903 = y + 7/10 - 7/10

Subtract the numbers

2.903 = y + 7/10 - 7/10

2.903 = y

Move the variable to the left

2.903 = y

y = 2.903

Answer:

Look at it this way. About two-thirds of the populace are thought to possess IQs between 85 and 115, which is to say, more or less average. That leaves about one sixth of the populace significantly below average and one sixth significantly above average.

Why such a large range for average — there’s a 30-point gap between 85 and 115? That’s because IQ tests measure only certain kinds of intelligence, and people who might be weak in some areas might be strong in other areas. Consider the difference between being book-smart and being street-smart. A person who is book-smart would be expected to score well on an IQ test but might not fare so well in a dangerous neighborhood after dark. A person who is street-smart would know better than to visit that neighborhood after dark but might not score so well on an IQ test.

Step-by-step explanation:

To calculate the value of the standard deviation in this equation, we must use Z-scores, therefore we are assuming that the distribution is regular.

At the twentieth percentile of a regular distribution, the z-score is -2.88. Using this information we can reverse-engineer the z-score calculation equation, [tex]z=\frac{n - x'}{s_{x} }[/tex]. x' being the mean of 100, n being the value of 85, z being the z score of -2.88 and s base x being the standard deviation.

[tex]-2.88=\frac{85-100}{s_{x}}[/tex].

The standard deviation is equivalent to 5.2083

Reflected along x axis

Translated 7 units to the right

Step-by-step explanation:

If a point (x, y) is reflected along the x axis, its x coordinate remains the same and the y coordinate is opposite (negated). The new point is at (x, -y)

If a point (x, y) is translated h units to the right, the new coordinate is (x+h, y).The transformation are as follows:

It is reflected along the x axis so that the new coordinates would be at A1 at (- 4, -4), B1 at (- 2, -2), C1 at (- 2, 1), D1 at (- 4, -1)

It is translated 7 units to the right, The new coordinates are A' at (3, -4), B' at (5, -2), C' at (5, 1), D' at (3, -1)

1. Since Hannah cannot buy a fraction of a cupcake, the maximum number of cupcakes she can buy is 5.

2. If Hannah buys the maximum amount of cupcakes (5 cupcakes), she will be able to buy 5 cookies with the remaining budget.

To find the maximum number of cupcakes Hannah can buy, we need to divide her budget by the cost of each cupcake:

1. Maximum cupcakes she can buy:

Maximum cupcakes = Budget / Cost per cupcake

Maximum cupcakes = $35 / $6 ≈ 5.83 (rounded down to the nearest whole number, as you cannot buy a fraction of a cupcake)

Since Hannah cannot buy a fraction of a cupcake, the maximum number of cupcakes she can buy is 5.

2. If she buys the maximum amount of cupcakes (5 cupcakes), we can find out how many cookies she can buy with the remaining budget.

Remaining budget after buying cupcakes:

Remaining budget = Total budget - (Number of cupcakes * Cost per cupcake)

Remaining budget = $35 - (5 * $6)

Remaining budget = $35 - $30

Remaining budget = $5

Now, we can calculate the number of cookies she can buy with the remaining budget:

Number of cookies = Remaining budget / Cost per cookie

Number of cookies = $5 / $1 = 5

Hence, if Hannah buys the maximum amount of cupcakes (5 cupcakes), she will be able to buy 5 cookies with the remaining budget.

Rate9681.1111%/year

Step-by-step explanation:

Solving our equation

r = 87130  (1800 × 0.5) = 96.81111111

r = 96.81111111

converting r decimal to a percentage

R = 96.81111111 × 100 = 9681.1111%/year

The interest rate required to

I hope I've helped you.

Explanation:-

From the given figure :

∠AOB = 50°

∠BOC = x+10°

∠COD = 2x+30°

∠DOE = 2x-10°

We know that

The sum of the angles lie on the same line = 180°

⇛ ∠AOB + ∠BOC + ∠COD + ∠DOE = 180°

⇛ 50°+x+10°+2x+30°+2x-10° = 180°

⇛ 5x+80° = 180°

⇛ 5x = 180°-80°

⇛ 5x = 100°

⇛ x = 100°/5

⇛ x = 20°

∴ x = 20°

Now,

The measure of ∠BOC = x+10°

= 20°+10°

= 30°

The measure of ∠COD = 2x+30°

= 2(20°)+30°

= 40°+30°

= 70°

The measure of ∠DOE = 2x-10°

=2(20°)-10°

= 40°-10°

= 30°

Answer:-

The measure of ∠BOC = 30°

The measure of ∠COD = 70°

The measure of ∠DOE = 30°

Remember:-The sum of the angles lie on the same line is 180°

Step-by-step explanation:

$15 is the normal cost for a single player.

Given that a game costs $132 for 12 people. That's $4 less per person than the normal cost for a single player.

We need to find the normal cost for a single player,

Let's denote the normal cost for a single player as "x" dollars.

According to the information given, the Light Storm group package costs $132 for 12 people, which means each person in the group pays $132 / 12 = $11.

We also know that the group package cost per person is $4 less than the normal cost for a single player. So, we can set up the following equation:

x - 4 = 11

Solving for "x":

x = 11 + 4

x = 15

Therefore, the normal cost for a single player is $15.
