Answer:
It depends on the number of charms that your bracelet can have.
here we need to count the number of selections that we have, and the number of options for each one of these selections.
So if we can have only one charm, we have only one selection, and for that selection, we have 9 options, then there are 9 different one-charm bracelets.
If each bracelet can have 2 charms then we have two selections.
For the first selection, we have 9 options,
If each charm can be selected only one time, then for the next selection we will have 8 options, now the total number of combinations is equal to the product between the numbers of options for each selection, so here the total number of combinations is:
C = 9*8 = 72
If we can select 3 charms, then:
first charm = 9 options
second charm = 8 options
third charm = 7 options
Total number of combinations = 9*8*7 = 504 combinations.
Notice that we can not give an exact answer because we do not know the number of charms in each bracelet and we do not know if a charm can be selected multiple times or only one, but here you could see the general way to solve this kind of problems.

Answer:
Step-by-step explanation:
you have a right triangle
to find the missing length(x) you will use
a^2+b^2=c^2
where c is the hypotenuse
49^2=25^2+x
x^2=49^2-25^2=2401-625=1776
x=[tex]\sqrt{1776}[/tex]=42.1

Find the mean, median, mode, and range of these numbers 75,95,90,95,60,95,75,95,90
Answer:
Mean=85.56, median=90, mode=95 and range=35
Step-by-step explanation:
To calculate the mean is the same as the average value in a data set. Median is data value separating the upper half of a data set from the lower half. The median is the data value separating the upper half of a data set from the lower half. The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number from the largest number.

Calculate the rate per litre at which a car uses petrol,if it uses 20l of petrol to travel 180 km
Answer:
1 L of petrol is used to travel 9 km.
Step-by-step explanation:
You can find the answers through the ratio method
20 L : 180 km
1 L : x
( x is the number we must find )
20 x = 180
x =
x = 9 km

"The sum of 4 and a number, divided by 2 is less than -6."
Answer:
[tex]\frac{4+n}{2} < -6[/tex], n < -16
Step-by-step explanation:
To write this into an inequality you need to recognize keywords. The first keyword is "sum" this means the two numbers must be added; so the first part of the inequality is 4+n. Then, it says the sum is "divided by" 2; this means both numbers must be put over two like [tex]\frac{4+n}{2}[/tex]. Finally, this is "less than" negative. Therefore, this must be an inequality with a sign opening towards -6. So the final answer is [tex]\frac{4+n}{2} < -6[/tex].
To solve the inequality isolate the variable. Multiply both sides by 2, so the new inequality is [tex]4+n<-12[/tex]. Next, subtract 4 from both sides. The answer is n < -16.
Find the solution of the system of equations.

2y = 32
Answer:
x=6 and y=−10
Step-by-step explanation:
You can also solve this system by elimination.)
6x+2y=16;2x−2y=32
Step: Solve6x+2y=16for x:
6x+2y+−2y=16+−2y(Add -2y to both sides)
6x=−2y+16

If answered soon i will give brainliest
Answer:
C. The value of a baseball card that is decreasing by $0.75 every 4 years.
Step-by-step explanation:
The exponential function would represent a mathematical function in the form of f(x) = a^x
where
x denotes the variable
a denotes the constant
So according to the given options, the option C would represent the exponential function
Hence, the option c is correct

In order to avoid power failures due to falling limbs and down trees, power companies will intentionally kill trees growing near their lines. Applying a chemical to slow the growth of the trees is cheaper than trimming, but the chemical kills some of the trees. Suppose that one such chemical would kill 25% of elm trees. The power company tests the chemical on 300 elms. Consider these an SRS from the population of all elm trees.
A) What are the mean and standard deviation of the proportion of trees that are killed?
B) Is it okay to use normal calculations for this problem? Explain.
C) What is the probability that at least 26% of the sample is killed?
Answer:
a)
Sample mean p = 25% = 0.25
standard deviation σ = 0.025
b)
YES, it okay to use normal calculations for this problem since the sample size is 300, hence np>10 and nq>10
so the conditions satisfied for normal approximation/calculations
c) the probability that at least 26% of the sample is killed is 0.6554
Step-by-step explanation:
Given the data in the question;
Suppose that one such chemical would kill 25% of elm trees. The power company tests the chemical on 300 elms
sample size n = 300
a) What are the mean and standard deviation of the proportion of trees that are killed?
Sample mean p = 25% = 0.25
standard deviation σ = √( pq / n ) = √( (0.25 × (1 - 0.25)) / 300 )
σ = √( (0.25 × 0.75) / 300 )
σ = √( 0.1875 / 300 )
σ = √0.000625
σ = 0.025
standard deviation σ = 0.025
b) Is it okay to use normal calculations for this problem?
YES, it okay to use normal calculations for this problem since the sample size is 300, hence np>10 and nq>10
so the conditions satisfied for normal approximation/calculations
c) the probability that at least 26% of the sample is killed
Now we are to find
P( P < 0.26 )
since its a normal approximation, we can convert p to z
so
P( P < 0.26 ) = P( Z < ( x-p / σ )
P( P < 0.26 ) = P( Z < ( 0.26-0.25 / 0.025 )
= P( Z < (0.01 / 0.025) )
= P( Z < 0.4 )
form z score table; P( Z < 0.4 ) = 0.6554
so
P( P < 0.26 ) = 0.6554
the probability that at least 26% of the sample is killed is 0.6554

SR = 12
Step-by-step explanation:
6/8 = (x-3)/(x+1)
8x-24 = 6x+6
simplify
2x = 30
x = 15
PR = 15 + 1 = 16
SR = 15 - 3 = 12
