The arrays found here are as follows; red: 1 blue 2 yellow 7. green. 16
What is the combination?Each of the different groups or selections can be formed by taking some or all of a number of objects, irrespective of their arrangments is called a combination.
We are given that Max has 2 red tiles, 3 blue tiles, 4 yellow
tiles, and 8 green tiles.
We can see that 4 and 9 could be 1 array. 2 and 18 can be another array. 3 and 12 could be another one. 6 and 6 could be another array. Lastly, 1 and 36 could be an array.
There should be a total of 5 arrays. If we include the 1 and 36 array, then it's 5, I'd you don't include it, then it's 4 arrays.
Hence, there are red: 1 blue 2 yellow 7. green. 16

Step-by-step explanation:
the volume of sphere is increaseing
at the Constant rate of 10cm²lsee-
Calculate the rate of increase of
the surface area
at the Instant
When the radus is 5cm. What
is the radius of the sphere when
the surface are is increasing at 2cm
Volume of a sphere:
V = 4/3 π r ³
Differentiate V with respect to time t :
dV/dt = 4π r ² dr/dt
Surface area of a sphere:
A = 4π r ²
Differentiate A with respect to t :
dA/dt = 8π r dr/dt
You're given that the volume is increasing at a constant rate, dV/dt = 10 cm³/s, so
10 cm³/s = 4π r ² dr/dt
Solve for dr/dt (the rate of change of the sphere's radius):
dr/dt = 5/(2π r ²) cm³/s
Substitute this into the equation for dA/dt :
dA/dt = 8π r (5/(2π r ²) cm³/s)
dA/dt = 20/r cm³/s
At the moment the radius is r = 5 cm, the surface area is increasing at a rate of
dA/dt = 20/(5 cm) cm³/s = 4 cm²/s
When the surface area is increasing at a rate of dA/dt = 2 cm²/s, the radius r is such that
2 cm²/s = 20/r cm³/s
which happens when the radius is
r = 20/2 (cm³/s) / (cm²/s) = 10 cm

Put the following equation of a line into slope-intercept form, simplifying all fractions.
3x+2y=14
Answer:
y = -3/2x + 7
Step-by-step explanation:
First, let's identify what slope-intercept form is: y = mx + b
We have:
3x + 2y = 14
Right away, we can see that we need to 1) move x to the right side of the equation and 2) simplify y.
1) To move x to the right side of the equation, subtract 3x from both sides.
2y = -3x + 14
2) To simplify y, divide both sides by 2. When dividing the right side by 2, you need to evaluate each component (3x and 14, not just one)
y = -3/2x + 7
This is your equation in slope-intercept form.
Hope this helps!

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
