Calculate the equivalent ratio 1.25 : 3.75 : 7.5
Answers
The equivalent ratio of 1.25 : 3.75 : 7.5 is 5 : 15 : 30.
To calculate the equivalent ratio of 1.25 : 3.75 : 7.5, we need to find a common multiplier that can be applied to all the numbers in the ratio to make them whole numbers. In this case, the common multiplier is 4 because it can be multiplied to each number to eliminate the decimals.
By multiplying each number in the ratio by 4, we get:
1.25 * 4 = 5
3.75 * 4 = 15
7.5 * 4 = 30
So the equivalent ratio of 1.25 : 3.75 : 7.5 is 5 : 15 : 30.
This means that the relative sizes or quantities represented by the original ratio are maintained in the equivalent ratio. For example, if we had 1.25 units of something, it would be equivalent to 5 units in the new ratio, and if we had 7.5 units, it would be equivalent to 30 units in the new ratio.

What is the measurement angle of angle C and D in the image
Answers
Answer:
c = 45 and e = 30
Step-by-step explanation:
Since we know that A = 45, B = 90, we can calculate C knowing that the total angle of a triangle is 180, so you do 180-45-90 = 45
Finding the angle C helps us find F by subtracting 45 from 180, since a straight line is 180 degrees, which is 135.
We know that E = 15, and what was said earlier about how the toal angle is 180 in a triangle, we can subtract 15 and 135 from 180, which is 30.

2·2·2·2 = 16
Step-by-step explanation:
everytime a number is raised by another, that means you are going to multiply the base number times itself as many times as the exponents tells you. this is a little but tricky to explain, so let me give you some examples:
2² → in this case the base number is 2 and the exponent is 2 as well, so you will multiply 2 times itself, 2 times:
2² = 2 · 2 = 4
2³ → in this case the base number is 2 and the exponent is 3, so you will multiply 2 times itself, 3 times:
2³ = 2 · 2 · 2 = 8
In the question asked, 2 is being raised by 4, so you will multiply 2 times itself, 4 times:
2^4 = 2·2·2·2 = 16
the same format will be used regardless of the base number and the exponent

On solving the provided question we can say that - probability distribution, E(X)= 47.5, V(X)= 128.75, \(E(X^{2})\) = 2605
What is probability distribution?A probability distribution is a mathematical function used in probability theory and statistics that estimates the likelihood that different possible experiment results will occur. The sample space and event probabilities are used to build a mathematical description of random occurrences.
E(X)= (20 * 0.05) + (30 *0.05)+ (40 * 0.35) + (50 * 0.20) + (60 *0.35)
= 1+ 1.5 + 14 + 10 + 21
= 47.5
V(X)= ((20-38)2 * 0.05) + ((30-38)2 *0.05)+ ((40-38)2 * 0.35) + (50-38)2 * 0.20) + ((60-38)2 *0.35)
= 16.2 + 3.2 + 1.4 + 28.8 +169.4
= 128.75
\(E(X^{2})\)=
=(202 * 0.05) + (302 *0.05)+ (402 * 0.35) + (502 * 0.20) + (602 *0.35)
= 20 + 45 + 560 + 500 +1260
=2605
\(V(X^2)\) = 2605 - ( 47.5)2

The formula for calculating the mean of a probability distribution is mean = (x * P(x)), where x denotes a potential result and P(x) denotes its probability.
How can the probability distribution be discovered?Distribution of Probabilities F(x) = P (X x) is a formula that describes it. Additionally, if the interval (a, b) is semi-closed, the probability distribution function is provided by the equation P(a X b) = F(b) - F (a). The range of a random variable's probability distribution function is always from 0 to 1.
Therefore, the mean for this distribution is: (0 * 0.04) + (1 * 0.24) + (4 * 0.35) + (5 * 0.16) + (7 * 0.21). mean = 0 + 0.24 + 1.4 + 0.8 + 1.47 mean = 4.81
Standard deviation = ((x - mean)2 * P(x)), where x is a conceivable outcome and P(x) is the probability of that outcome, gives the standard deviation of a probability distribution.
This gives us the following standard deviation for this distribution: standard deviation = ((((0 - 4.81)2 * 0.04) + ((1 - 4.81)2 * 0.24) + ((4 - 4.81)2 * 0.35) + ((5 - 4.81)2 * 0.16) + ((7 - 4.81)2 * 0.21)) (23.0461) 4.8114 is the standard deviation.
To two decimal places, round:
mean = 4.81 4.81 is the standard deviation.
Therefore, the provided probability distribution's mean and standard deviation are 4.81 and 4.81, respectively.

Step-by-step explanation:
When ordering a list of numbers by hand, it is convenient to convert them to the same form. Decimal equivalents are easily found using a calculator.
OrderThe attachment shows the ordering, least to greatest, to be ...
\(\dfrac{28}{9}.\ \sqrt{19},\ \sqrt[3]{88}\)
__
Additional comment
We know that √19 > √16 = 4, and ∛88 > ∛64 = 4, so the fraction 28/9 will be the smallest. That leaves us to compare √19 and ∛88, both of which are near the same value between 4 and 5.
One way to do the comparison is to convert these to values that need to have the same root:
√19 = 19^(1/2) = 19^(3/6) = sixthroot(19³)
∛88 = 88^(1/3) = 88^(2/6) = sixthroot(88²)
The roots will have the same ordering as 19³ and 88².
Of course, these values can be found easily using a calculator, as can the original roots. By hand, we might compute them as ...
19³ = (20 -1)³ = 20³ -3(20²) +3(20) -1 = 8000 -1200 +60 -1 = 6859
88² = (90 -2)² = 90² -2(2)(90) +2² = 8100 -360 +4 = 7744
Then the ordering is ...
28/9 < 19³ < 88² ⇒ 28/9 < √19 < ∛88
Answer:
the ordering is
28/9 < 19³ < 88² ⇒ 28/9 < √19 < ∛88
