Answer:

  a) Cat

  b) 8

  c) 6

Step-by-step explanation:

a) Each line contains one large square, at least. The smallest additional area is on the Cat line. Apparently, the fewest people preferred cats.

__

b) The smaller symbols appear to represent 1/4, 1/2, and 3/4 of the larger square. On that basis, we can add all of the symbols to discover there are a total of 10 of them:

  1 1/4 +1 3/4 +2 1/2 +1 1/2 + 3 = 8 + (1/4 +3/4) +(1/2 +1/2) = 8 +1 +1 = 10

Since 10 symbols represent 80 people, each large square symbol must represent 8 people.

__

c) The number preferring dogs is (1 3/4)(8) = 14. The number preferring giraffes is (2 1/2)(8) = 20. Then 20 -14 = 6 more people preferred giraffes.

We want to find the probability that Bob will randomly draw $30 in tokens. We will find that the probability is P = 1/6 = 0.167

The only case where he draws $30 randomly is when:

Then we need to find the probabilities for these two events.

For the first one, the probability will be equal to the quotient between the number of $5 tokens and the total number of tokens in the cup. There are 6 tokens in the cup and 2 of these are $5 tokens, then the probability is:

p = 2/6 = 1/3

For the second event the probability is computed in the same way, he has two tokens in his pocket and one of them is a $25 token, then the probability is:

q = 1/2

The joint probability, the probability that both of these events happen at the same time, is given by the product of the individual probabilities, so we get:

P = p*q = (1/3)*(1/2) = 1/6 = 0.167

So the probability that he draws $30 in tokens is P = 1/6 = 0.167.

Answer:

[tex] \displaystyle WY = 24[/tex]

Step-by-step explanation:

refer the attachment

remember that,

the diagonals of Parallelogram bisect each other so WA=AY

thus our equation is

[tex] \displaystyle {x}^{2} - 24 = 2x[/tex]

move left hand side expression to right hand side and change its sign:

[tex] \displaystyle {x}^{2} - 2x - 24 =0[/tex]

rewrite 2x and 4x-6x:

[tex] \displaystyle {x}^{2} + 4x -6x - 24 =0[/tex]

factor out x:

[tex] \displaystyle x ({x}^{} + 4) -6x - 24 =0[/tex]

factor out -6:

[tex] \displaystyle x ({x}^{} + 4) -6(x + 4) =0[/tex]

group:

[tex] \displaystyle ({x}^{} + 4) (x - 6) =0[/tex]

recall that,

When the product of factors equals 0 then at least one factor is 0 so

[tex] \displaystyle \begin{cases} {x}^{} + 4 = 0 \\ x - 6 =0 \end{cases}[/tex]

[tex] \displaystyle \begin{cases} {x}^{} = - 4\\ x =6 \end{cases}[/tex]

since the length cannot be negative negative x isn't available

therefore

[tex] \displaystyle \therefore x = 6[/tex]

since WA and AY are the part of WY we acquire:

[tex] \displaystyle WY = {x}^{2} - 24 + 2x[/tex]

substitute the got value of x:

[tex] \displaystyle WY = {6}^{2} - 24 + 2.6[/tex]

simplify square:

[tex] \displaystyle WY = 36 - 24 + 2.6[/tex]

simplify multiplication:

[tex] \displaystyle WY = 36 - 24 + 12[/tex]

simplify addition:

[tex] \displaystyle WY = 48- 24[/tex]

simplify substraction:

[tex] \displaystyle WY = 24[/tex]

hence,

[tex] \displaystyle WY = 24[/tex]

Diagonals bisect each other

Take it positive

Answer:

Step-by-step explanation:

The inverse function of [tex]f(x) = 1.5^x + 4[/tex] is [tex]f^{-1}(x) = \log1.5(x - 4)[/tex]

In other words, the required answer is  [tex]f^{-1}(x) = \log1.5(x - 4)[/tex]

To find the inverse of the function[tex]f(x) = 1.5^x + 4[/tex], we need to swap the roles of x and y and solve for y.

Start with the original function:

[tex]y = 1.5^x + 4[/tex]

Swap x and y:

[tex]x = 1.5^y + 4[/tex]

Solve for y:

Subtract 4 from both sides:

[tex]x - 4 = 1.5^y[/tex]

Take the logarithm (base 1.5) of both sides:

[tex]\log1.5(x - 4) = y[/tex]

Rewrite the equation with y as the subject:

y = log1.5(x - 4)

Therefore, the inverse function of [tex]f(x) = 1.5^x + 4[/tex] is [tex]f^{-1}(x) = \log1.5(x - 4)[/tex]

In other words, the required answer is  [tex]f^{-1}(x) = \log1.5(x - 4)[/tex]

Answer: 500 meters

Step-by-step explanation:

Since he won the gold medal in the men’s 500 m kayak race, with a time of 1 min 37.9 s, the speed will be:

= Distance/Time

= 500m/1 min 37.9s

= 500m/97.9s

= 5.11m/s

Since he also won the bronze medal in the 1000 m race, with a time of 3 min 28.2s, the speed will be:

= Distance/Time

= 1000/3 min 28.2s

= 1000m/208.2s

= 4.80m/s

Therefore, he rowed with greater speed in the 500 meters.

Answer:

16.97 ft

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Side B = 21 ft

Side c = 27 ft

As we know, formula for right triangle is as follows,

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]a^{2} = c^{2} - b^{2}[/tex]

So, by putting the value in the formula, we get,

[tex]a^{2} = 27^{2} - 21^{2}[/tex]

[tex]a^{2}[/tex] = 729 - 441

[tex]a^{2}[/tex] = 288

a = 16.97 ft

Hence, the length of the side  for the right triangle is 16.97ft.
