Mathematics
1 answer:
Sophie [7]3 years ago
3 0

Answer:

x=3

Step-by-step explanation:

The equation will be 3+6x=21 since we know that the soft drink costs 3 dollars and he bought 6 candy bars(6 times x or 6x). We also know that the total cost for this merchandise is 21 dollars. Now you solve the equation! First subtract 3 from both sides(since the inverse for addition is subtraction we SUBTRACT 3 from bothe sides). You are left with 6x=21-3 or 6x=18. Now you divide Each side by 6(because the inverse operation of multiplication is division). You have the answer! x=18/6 or x=3! Hope it helped!!

What is the probability that a person who is above 35 years old has a hemoglobin level of 9 or above?
lorasvet [3.4K]

Answer:

Option C. P=0.531

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.  

The size of the sample space is the total number of possible outcomes  

The event space is the number of outcomes in the event you are interested in.  

so  

Let

x------> size of the event space  (total person's hemoglobin level of 9 or above with age above 35 years)

y-----> size of the sample space  (total person's age above 35 years)

so

P=\frac{x}{y}

In this problem we have

y=162

Complete the table to find the total person's hemoglobin level of 9 or above (person's age above 35)

Let

y------> total person's hemoglobin level between 9 and 11 (person's age above 35)

y+76+40=162

y=46

Find the value of x

x=46+40=86

substitute the values

P=\frac{86}{162}=0.531

Claire has $300 Is an account. She decides she is going to take out $25 each month.
Elena-2011 [213]
Recursive equation would be f(x+1) = f(x) - 25 with f(0) = 300

Explicit equation would be f(x) = -25x + 300

And graph would looks like this:

A culture started with 1,000 bacteria. After 3 hours, it grew to 1,100 bacteria. Predict how many bacteria will be present after
ss7ja [257]
The general equation for exponential growth can be written as:
x_{t} = x_{0} (1+r)^{t}
where r is the growth rate.
Plugging in the given values, we get:
1100=1000(1+r)^{3}
Therefore
(1+r)^{3}=1.1
giving
1+r= \sqrt[3]{1.1} =1.0323
The predicted number of bacteria after 17 hours is given by:
1000(1.0323)^{17}=1716
