Given that a/b = 3/5 and b/c = 3/4.
Find a : b : c
Answer:
a : b : c = 9 : 15 : 20
Step-by-step explanation:
Here, b is common to both the ratios. In order to find the combined ratio of a, b and c, it is required to make the b ratio same in the given ratios.
Therefore,
[tex] \frac{a}{b} = \frac{3}{5} = \frac{3 \times 3}{5 \times 3} = \frac{9}{15} \\ \\ \frac{b}{c} = \frac{3}{4} = \frac{3 \times 5}{4 \times 5} = \frac{15}{20} \\ \\ \implies \: a : b : c = 9 : 15 : 20[/tex]

Find the surface area of the prism. The surface area is
Answer:
132m^2
Step-by-step explanation:
Area=10x5+3x4x2/2+10x3+4x10
=50+12+30+40
=132
Answer: 132 meters squared
Step-by-step explanation:
We add all the sides of the shape:
Three quadrangular sides:
3 x 10 = 30
4 x 10 = 40
5 x 10 = 50
30 + 40 + 50 = 120
Two triangular sides:
3 x 4 / 2 = 6
3 x 4 / 2 = 6
6 + 6 = 12
We add all up:
120 + 12 = 132 meters squared
A bakery sells 5394 donuts in 2010. The bakery sells 10,874 donuts in 2015. Write a linear model that represents the number y of donuts that the bakery sells x years after 2010.
Answer:
y = 1096x + 5394
Step-by-step explanation:
Given that
The bakery sells 5394 donuts in 2010
And, the bakery sells 10,874 donuts in 2015
We need to write the linear model
So here
we assume that the x be the no of years after 2010
And, y be the no of donuts
Now
x_1 = 0, y_1 = 5394
x_2 = 5, y_2 = 10874
Now the slope is
m = (y_2 - y_1) ÷ (x_2 - x_1)
= (10874 - 5394) ÷ (5 - 0)
= 1,096
Now
y - y_1 = m(x - x_1)
y - 5394 = 1096(x - 0)
y - 5394 = 1096x - 0
y = 1096x + 5394

5.6 cm
Answer:
6.47
1.618 x 4 = 6.47
Step-by-step explanation:
Answer:
The length of golden rectangle is 6.5 cm.
Step-by-step explanation:
Definition of golden rectangle
The Golden Rectangle, also known as the perfect rectangle by some, is a rectangle with the Golden Ratio as its length to width ratio. Many people consider this to be one of the most visually appealing geometric shapes. Many works of art and architecture contain it.
Given the width of golden rectangle= 4 cm
and the golden ratio= 1.618
The golden ratio is the ratio of length and width [tex]l/b=1.618[/tex]
[tex]l=1.618*b\\=1.618*4\\=6.472 cm[/tex]
Now length of the rectangle is up to nearest tenth point=6.5 cm
Hence the length= 6.5 cm

Answer:
x = 60°
Step-by-step explanation:
First find <E by applying the angles of intersecting chords theorem.
Based on the theorem, we would have the following equation:
m<E = ½(arc CA + arc BD)
Substitute
m<E = ½(170° + 70°)
m<E = ½(240)
m<E = 120°
Let's find x:
x = 180° - m<E (supplementary angles)
x = 180° - 120° (substitution)
x = 60°

Assume that 200 babies are born to 200 couples treated with the XSORT method of gender selection that is claimed to make girls more likely. Preliminary results from a test of the XSORT method of gender selection involved 200 couples who gave birth to 115 girls and 85 boys. At significance level of 0.1, test whether the proportion of girl births after the treatment is greater than the 50% that occurs without any treatment (optional: show your work of the hypothesis testing in paper). Answer the next three questions
a. test statistic =
b. p-value =
c. What is your decision?
Answer:
a) test statistic = 2.12
b) p-value = 0.017
c) we reject the Null hypothesis
Step-by-step explanation:
Given data :
N = 200
girls (x) = 115 , Boys = 85
p = x / n = 115 / 200 = 0.575
significance level ( ∝ ) = 0.1
aim : test whether the proportion of girls births after the treatment is greater than 50% that occurs without any treatment .
A) Determine the test statistic
H0 : p = 0.5
Ha : p > 0.5
to determine the test statistic we will apply the z distribution at ( ∝ ) = 0.1
Z - test statistic = ( 0.575 - 0.5) / [tex]\sqrt{0.5*0.5 / 200}[/tex] = 2.12
b) determine the p-value
The P-value can be determined using the normal standard table
P-value = 1 - p(Z< 2.12 ) = 1 - 0.9830 = 0.017
c) Given that the p value ( 0.017 ) < significance level ( 0.1 )
we will reject the H0 because there is evidence showing that proportion of girls birth is > 50%
Suppose that you are about to purchase a car and have narrowed your choices to two models --Model A and Model B. All things are about equal, such as price, options, even the average annual maintenance costs. You find an owner survey in an auto magazine that indicates that the standard deviation of maintenance costs is smaller for Model B. Based on this information, which of the following statements is most appropriate?
A. Model B with the smaller standard deviation is preferable, because the smaller value implies that the mean is a more reliable representation of maintenance costs.
B. Model A with the larger standard deviation is preferable. Cecause the larger value implies a smaller amount of variation in the data
C. Neither of the models are good since both standard deviations are not equal to 0. B 2
D. They are equally acceptable, because standard deviations are not useful for comparisons of data sets.
E. Cannot determine based on the information provided.
Answer:
A. Model B with the smaller standard deviation is preferable, because the smaller value implies that the mean is a more reliable representation of maintenance costs.
Step-by-step explanation:
The standard deviation is a measure of the variability of a dataset about a mean value. Larger values of standard deviation implies that the values varies Hugely about the mean whole smaller variability measure values mean that the data only varies a little about the mean. The implication of having a large variability value is that, low and high values in the data can be very different from the mean values, hence, lowering the reliability of Mean value. The lesser varibality gives the mean more reliability as a measure of centre

What is Algebra?Algebra is the study of graphic formulas, while logic is the interpretation among those signs.
You can approximate e by substituting large values for n into the expression.
Let the infinity be the largest number.
A. (1 – 1/n)ⁿ
Substitute n = ∞, then the value of the expression will be
[tex]\Rightarrow \left (1 - \dfrac{1}{\infty} \right)^{\infty}\\\\\Rightarrow \left (1 - 0 \right)^{\infty}\\\\\Rightarrow 1[/tex]
B. (1 + n)ⁿ
Substitute n = ∞, then the value of the expression will be
[tex]\Rightarrow \left (1 + \infty \right)^{\infty}\\\\\Rightarrow \infty^{\infty} \\\\\Rightarrow \infty[/tex]
C. (1 – n)ⁿ
Substitute n = ∞, then the value of the expression will be
[tex]\Rightarrow \left (1 - \infty \right)^{\infty}\\\\\Rightarrow \infty^{\infty} \\\\\Rightarrow \infty[/tex]
D. (1 + 1/n)²
Substitute n = ∞, then the value of the expression will be
⇒ (1 + 1/∞)²
⇒ (1 + 0)²
⇒ 1²
⇒ 1
Then the value of the expression A, B, C, and D will be 1, ∞, ∞, and 1.
