On one island there lived two friends, Ana and Banana. One of them always tells the truth, while the other always lies. When asked which one is the liar among them, they said: Ana: "Banana ate ten apples yesterday, and he is telling the truth." Banana: "No, I ate five apples yesterday, and Ana is lying." How many apples did Banana eat yesterday?

Answers

Answer:

Number of apples ate = 5

Step-by-step explanation:

Fact:

One of them always tells the truth, while the other always lies.

To find how many apples banana ate, we have to figure out who is lying between Ana and Banana.

Ana: "Banana ate ten apples yesterday, and he is telling the truth."

If Ana is telling the truth, that means Banana is also telling the truth because of the statement (... and he is telling the truth).

This is not possible as one of them must be lying. The only option left is that Ana is lying.

Since Ana is lying, it means banana is telling the truth.

Banana: "No, I ate five apples yesterday, and Ana is lying."

Number of apples ate = 5

Answers

Answer: y = -1/4 * x - 4

Explanation:
Slope intercept form : y = mx + b
m = slope & b = y intercept
y = mx + b
y = -1/4(x) + b
y = -1/4(x) - 4

-1/4 is slope
-4 is y intercept

what is the effect on the graph of the function f(x)=x^2 when f(x) is changed to f(x)+9

Answers

Given:

The function is

[tex]f(x)=x^2[/tex]

This function is changed to f(x)+9.

To find:

The effect on the graph of the function.

Solution:

The translation is defined as

[tex]g(x)=f(x)+b[/tex]                .... (1)

Where, b is vertical shift.   If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

The new function is

[tex]g(x)=f(x)+9[/tex]           ...(2)

From (1) and (2), we get

[tex]b=9[/tex]

So, the graph of f(x) shifts 9 units up as shown in the below graph.

Answer:

slope = -10/7

Step-by-step explanation:

co-ordinates = (6,-2) (5,-4)

slope = (y² - y¹) / (x² - x¹)

slope = (-4 - 6) / (5 - (-2))

slope = (-10) / (5+2)

A zoo has an equal number of African elephants and Asian elephants. The African elephants cost £11 per day to feed and the Asian elephants cost £9 per day to feed. The total daily bill for feeding all of the zoo's elephants is £1000. How many elephants does the zoo have?

Answers

Answer:

The zoo has 50 African elephants and 50 Asian elephants which means that there are 100 elephants.

Step-by-step explanation:

From the information provided, you can say that the result of adding up the African elephants cost to feed per day for the number of African elephants plus the Asian elephants cost to feed per day for the number of Asian elephants would be equal to £1000, which can be expressed as:

11x+9y=1000, where:

x is the number of African elephants

y is the number of Asian elephants

Now, as the statement indicates that the zoo has an equal number of African elephants and Asian elephants, this means that x=y and you can replace y with x and solve for x:

11x+9x=1000

20x=1000

x=1000/20

x=50

According to this and considering that the zoo has an equal number of African elephants and Asian elephants, the answer is that the zoo has 50 African elephants and 50 Asian elephants which means that there are 100 elephants.

Assume that 5% of all athletes use drugs, 4% of all tests on drug-free athletes yield false positives, and 10% of all tests on drug users yield false negatives. Define the events as follows: Free: an athlete is drug free. User: an athlete is a drug user. Positive: an athlete is tested positive Negative: an athlete is tested negative.
