Answer:
39.1
Step-by-step explanation:
31.7 + 42.8 + 26.4 = 100.9
35 times 4 = 140
140 - 100.9 = 39.1
Answer:
[tex]mean = \frac{31.7+42.8+26.4+x}{4} \\\\35 = \frac{31.7+42.8+26.4+x}{4} \\\\\\35*4 = 31.7+42.8+26.4+x \\\\140 = 100.9 + x\\\\x= 39.1[/tex]

What is the inverse of f(x)=1.5^x+4
Answers
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]

10. C= 5
11. B= 2 V55 (2 square root of 55)
12. C= 2 V5
13. A= V5.39
Explanation:
10. a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2 (add 9 and 16)
25=c^2
V25= Vc^2 (take the square root of both sides to get):
5=c
11. 6^2+b^2=16^2
36+b^2=256 (256-36)
b^2=220 (square root, 220 cannot be simplified so you factor it and get):
b= 2 V55
12. 4^2+2^2=c^2
16+4=c^2
20=c^2 ( square root it then factor)
2 V5 = c
13. a^2+3.5^2=4.2^2
a^2+12.25=17.64 (subtract 17.64 and 12.25)
a^2=5.39 ( square root/ cannot be simplified so the square root of 5.39 is your answer)

what is the missing exponent?
17 / 17^4 = 17^8
Answers
Answer:
The missing exponent is 12.
Step-by-step explanation:
Whenever you divide same-base exponents, you keep the base numbers the same and subtract the exponents.
The only number subtracted by 4 that would give you 8 is 12.
Or, if the numbers are larger, it is must easier to add the exponent in the answer to the number in the equation.
For example,
[tex]17^4+17^8=17^1^2[/tex]
Therefore, the missing exponent is 12.
Because: [tex]17^1^2/17^4=17^8[/tex]

In the 2004 Summer Olympics, Adam van Koeverden of Oakville, Ontario, won two medals. He won the gold medal in the men’s 500 m kayak race, with a time of 1 min 37.9 s. He also won the bronze medal in the 1000 m race, with a time of 3 min 28.2 s. In which race did he row with greater speed?
Answers
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.
Note that 60seconds = 1 minute

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.

Bob has a coin cup with four $1 tokens and two $5 tokens in it. He also has two $10 tokens and one $25 token in his pocket.
He randomly draws a token froin the cup, and then randomly draws a token from his pocket. What is the probability that he
will draw $30 in tokens?
OB.
. В
Answers
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
Finding the probability.
The only case where he draws $30 randomly is when:
He takes one $5 token from the coin cupHe takes the $25 token from his pocket.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.
