In the diagram, there is an object with 6 triangular faces. On each corner there is a number (two are shown). The sum of the numbers on the corners of each triangle is the same. What is the sum of all 5 numbers?
Answer:
17
Step-by-step explanation:
Let the two "middle" vertexes be x1 and x2, and let the "lower" vertex be y. We know that
[tex]1 + 5 + x1 = 1 + 5 + x2[/tex]
Therefore x1=x2. We'll call that value just x.
But now we have to be careful, because
[tex]5 + x + y = x + x + y[/tex]
Simplifying we can get the value of x:
[tex]x = 5[/tex]
Now, substituting back in, we get
[tex]1 + 5 + 5 = 5 + 5 + y \\ y = 1[/tex]
So, the sum of all vertexes is equal to
[tex]2 \times 1 + 3 \times 5 = 17[/tex]
The sum of all the five numbers is 17
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the top and bottom vertex of the object be A
So , the vertex number A = 1
There are 2 vertex for the object
Now , the value of 2A = 2 x 1
2A = 2
And , there are 3 base points for the triangular object with the base number as 5
Let the base number be B = 5
There are 3 base points
3B = 3 x 5
3B = 15
So , the total sum of the numbers = 2A + 3B
2A + 3B = 2 + 15
= 17
Hence , The sum of all the five numbers is 17

Step-by-step explanation:
the question requires us to solve for the degree of freedom of this test.
we have this information below to answer this question
number on time = 90 95 85 60
sample size = 100 120 100 10
from this we can see that we have two rows, each row contains four piece of data, which gives us 4 columns

Step-by-step explanation:
A cell phone provider classifies its customers as Low users (less than 400 minutesper month) or High users (400 or more minutes per month). Studies have shownthat 80% of the people who were Low users one month will be Low users the nextmonth, and that 70% of the people who were High users one month will be Highusers the next month.
(a) Set up the 2x2 stochastic matrix with columns and rows labeled L and H that displays these transitions
(b) Suppose that, during the month of January, 50% of the customers were Low users. What percent of the customers will be Low users in February? In March? (Type an integer or decimal for each matrix element.)
1. The stochastic matrix for the given transitions is:
[tex]T = \left[\begin{array}{ccc}0.80 & 0.20\\0.30&0.70 \end{array}\right]\\[/tex]
2. 40.0% people in February and 32.0% people in March will be the low users if there are 50% low users in January.
It is given that,
80% of the people who were Low users one month will be Low users the next month.
That means for the transition low-low (L-L)
p = 0.80
So, for Low-high transition (L-H)
p = 1-0.80 = 0.20
It is also given that 70% of the people who were High users one month will be High users the next month.
That means, p = 0.70 for the transition high-high (H-H)
Then for H-L transition, p = 1-0.70 = 0.30
(a) The 2x2 stochastic matrix for these transitions is:
[tex]T = \left[\begin{array}{ccc}0.80 & 0.20\\0.30&0.70 \end{array}\right]\\[/tex]
(b) Given that 50% users are the low users in month of January.
[tex]\text{Percent of the customers will be Low users in February}= (\text{low users in month of January} \times \text{Probability of L-L transition.}) \times 100\%[/tex]= (0.50 x 0.80)x100%
= 0.4x 100%
=40.0%
Now, the percentage of people who will be low users in the month of march = (low users in February x probability of L-L transition)x100%
=(0.40x0.80)x100%
=0.32x100%
=32.0%
Hence, the percentage of people who will be low users in the month of February and in the month of March are 40.0% and 32.0% respectively.
Therefore, the results are:
1.2x2 stochastic matrix for the transitions is as:
[tex]T = \left[\begin{array}{ccc}0.80 & 0.20\\0.30&0.70 \end{array}\right]\\[/tex]
2. The percentage of people who will be low users in the month of February and in the month of March are 40.0% and 32.0% respectively.

Answer:
The father is 54 years old
Step-by-step explanation:
Well from the ratio 9:4
We know the son is 24
we can divide 24/4 to get 6
now we know we have to multiply by 6 on each side of the ratio to get the final result
54:24
Answer:
54 years old
Step-by-step explanation:
Because the son is 24 years old, we know that that is 6 times the '4' in the ratio 9:4 therefore if we do 6*9=54 that is the age of his father!

Answer:
(2,4)
Step-by-step explanation:
The coordinate of A is (2,-4) currently. If we reflect that point over the x-axis, the y coordinate will change into the opposite sign. Because the y coordinate is -4, it will change to - (-4) = 4. Therefore, the coordinate of A' would be (2,4).
A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 421 gram setting. It is believed that the machine is underfilling the bags. A 26 bag sample had a mean of 413 grams with a standard deviation of 24. Assume the population is normally distributed. A level of significance of 0.02 will be used. Find the P-value of the test statistic. You may write the P-value as a range using interval notation, or as a decimal value rounded to four decimal places.
Answer:
The p-value is approximately 0.0508
Step-by-step explanation:
The given parameters are;
The expected mass of banana chips bag filled by the machine, μ = 421 gams
The number of bags in the sample of bags filled by the machine, n = 26 bags
The mean mass of the bags in the sample, [tex]\overline x[/tex] = 413 grams
The standard deviation of the mass in the bags, s = 24 grams
The level of significance, α = 0.02
The null hypothesis, H₀; μ = 421 grams
The alternative hypothesis, Hₐ; μ < 421 grams
The test statistic is given as follows;
[tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex]
We get;
[tex]t=\dfrac{413-421 }{\dfrac{24}{\sqrt{26}}} \approx -1.6996731712[/tex]
The t-value = -1.6996731712
The degrees of freedom df = n - 1 = 26 - 1 = 25
From an online source, we get the critical-t = 2.166587
The p-value is obtained using an online source as p(t ≤ -1.6996731712) = 0.0508
From the p-value table, we get
0.05 < p < 0.1

Melanie is going to invest $45,000 and leave it in an account for 20 years. Assuming
the interest is compounded continuously, what interest rate, to the nearest
hundredth of a percent, would be required in order for Melanie to end up with
$142,000?
Answer:
Rate of interest r = 5.20% (Approx.)
Step-by-step explanation:
Given:
Amount invested p = $45,000
Final amount A = $142,000
Number of year = 20
Find:
Rate of interest r
Computation:
A = p[1+r]ⁿ
142,000 = 45,000[1+r]²⁰
3.1556 = [1+r]²⁰
r = 5.194
Rate of interest r = 5.20% (Approx.)

Step-by-step explanation:
A (-9, -6)
translation: left 2 units, up 6 units
If the point is moving left, this will change the x value. We are moving left which is towards the negative side of the graph. This means we will be subtracting 2 from the x-value.
-9 - 2 = -11
This is our new x-coordinate.
If the point is moving up, this will change the y-value. We are moving up, which is towards the positive side of the graph. This means we will be adding 6 from the y-value.
-6 + 6 = 0
This is our new y-coordinate.
Let's put our new coordinates together.
(-11, 0)
This is your answer.

A store gives customers a markup of 13%. If the store sells a belt for $25, what was the wholesale price paid for the belt by the store?
Answer:
$22.12
Step-by-step explanation:
Let x be the wholesale price (the price before adding the markup).
The markup is 13%, so 13% of x is added to x.
x + 13%x = $25
x + 0.13x = 25
1.13x = 25
x = 25/1.13
x = 22.12
