Suppose that 60% of the people who inquire about investments at a certain brokerage firm end up investing in stocks. The probability that a person who inquires about investments at this firm will invest in stocks or bonds (or both) is 66%.

60% invest in stocks

50% invest in bonds

44% invest in both bonds and stocks

Percent (only stock) = 60% -44%

Percent (only stock) = 16%

Percent (only bond) = 50% - 44%

Percent (only bond) = 6%

Percent (both) = 44%

Total = 16% + 6% + 44%

Total = 66%

Answer:

true

Step-by-step explanation:

A ratio or value that may be stated as a fraction of 100 is called a percentage.

A percentage is a figure or ratio that can be stated as a fraction of 100 in mathematics. If we need to determine a percentage of a number, multiply it by 100 and divide it by the total. So, a part per hundred is what the percentage refers to. Percent signifies for every 100. The sign "%" is used to denote it.

The value must be divided by the entire value, and the resulting number must then be multiplied by 100 to get the percentage.

The simplest way to use percentages is to compare two numbers, with the second number being rebased to 100.

Therefore, the answer is 25%.

a. 5 + 7n is the algebraic expression for 7 more than the product of 5 and n

The expression needed to indicate the value of 5 added to the product of 7 and n is "5 greater than the product of 7 and n."

The equation 7n represents the product of 7 and n, and the expression 5 + 7n is obtained by adding 5 to 7n.

This is the proper algebraic expression for the phrase that was given.

It follows that 5 + 7n = 5 + 21 = 26, which is 5 more than the sum of the products of 7 and 3. As an illustration, if we substitute a value of 3 for n, the expression 7n would equal 21.

Because option b is a product of 5 and (7+n), which is not equivalent to 5 greater than the product of 7 and n, the other choices are incorrect.

The product of option c and (5+n) is 7, but it also does not equal 5 greater than the product of 7 and n.

A sum of 5, 7, and n makes up option d, which also does not equal 5 greater than the result of the product of 7 and n.

Answer:

BE = 24

Step-by-step explanation:

These triangles are similar because of AA (Angle, Angle)

The given gives us a pair of parallel sides, allowing us to see that angles C and B are congruent due to being alternate interior angles.

Furthermore, we see that <AEB = <CEB due to vertical <'s being =

Next, we must set up a proportion;

If we create a proportion between the triangles, we must divide corresponding sides;

52/26 = 5x -7 / 2x+2 because we divided both triangles by using the same corresponding sides divided by the same corresponding side.

Simplify 52/26 to 2 and we get that 2 = 5x-7 / 2x+2

Multiply both sides by 2x+2 to get 4x+4 = 5x-7

Subtract 4x from both sides and add 7 from the right side to isolate x and get x=11

Finally, substitute the value of 11 for x into BE 2(11) + 2 and get 22 + 2 =24

The sum of the additive inverse of 29 and 61 is equal to -90.

The sum of the additive inverse of two numbers is equal to zero. The additive inverse of a number is the (opposite) number which when added to the original number yields zero. The formula for calculating the additive inverse of a number is additive inverse (x) = - x. The additive inverse of 29 and 61 can be calculated using the formula, additive inverse (29) = -29 and additive inverse (61) = -61.

Therefore, the sum of the additive inverse of 29 and 61 will be -29 + -61 = -90. This can be confirmed by adding 29 and 61 which will yield 90 and then subtracting 90 from zero to yield -90. In other words, the sum of the additive inverse of 29 and 61 is equal to -90.
