Q1. Three types of coffee beans, A, B and C, are blended in the ratio 3: 5:7 to make a bag of coffee
powder. Given that the bag contains 45 kg of coffee powder, find the mass coffee beans A in the
mixture?​

Answers

Answer:

Mass of coffee A beans = 9 kg

Step-by-step explanation:

Coffee A = 3

Coffee B = 5

Coffee C = 7

A : B : C = 3 : 5 : 7

Total ratio = 15

Total mass of the bag = 45 kg

find the mass coffee beans A in the mixture?

Mass of coffee A beans = ratio of coffee A / total ratio × total mass of the bag

= 3/15 × 45

= 1/5 × 45

= (1 * 45)/5

= 45/5

= 9 kg

Mass of coffee A beans = 9 kg

Mass of coffee B beans = ratio of coffee B / total ratio × total mass of the bag

= 5/15 × 45

= 1/3 × 45

= 45/3

= 15 kg

Mass of coffee C beans = ratio of coffee C / total ratio × total mass of the bag

= 7/15 × 45

= (7*45)/15

= 315/15

= 21 kg

The area of the rectangle is 65 yd^2,and the length of the rectangle is 3 yd less than twice the width. Find the dimensions of the rectangle

Answers

Answer: Length = 10cm

Width = 6.5cm

Step-by-step explanation:

Let the width of the rectangle be represented by x.

Therefore, the length of the rectangle will be: = (2 × x) - 3 = 2x - 3

Therefore area of a rectangle = length × width

x(2x - 3) = 65

2x² - 3x = 65

2x² - 3x - 65 = 0

2x² + 10x - 13x - 65 = 0

2x(x + 5) - 13(x + 5) = 0

(2x - 13)(x + 5) = 0

2x - 13 = 0

2x = 13

x = 13/2

x = 6.5

Width = 6.5cm

Length = 2x - 3

= 2(6.5) - 3

= 13 - 3

= 10cm

Therefore, the length of the rectangle is 10cm and the width is 6.5cm.

Answers

Answer:

9.32

10.116

Step-by-step explanation:

each corner is a right corner so were going to subtract 58 from 90 because all right corners are 90 degrees

90-58=32  answer A 32

after that we know that all triangles have to equal 180 so now we subtract

180-58=122 122-58=64

we subtract  58 two times because we  have 2 of the same angles

next we know that the smaller angle is 32 so now we subtract again

180-32=148 148-32=116 so y is 116

Of 118 randomly selected adults, 29% said that they had high blood pressure. Find the 95% confidence interval for the proportion of all adults that have high blood pressure. State the interval and write a sentence explaining the information in the interval in the context of the problem.

Answers

Answer:

(0.208 ; 0.372)

Step-by-step explanation:

phat = 29% = 0.29

Sample size, n = 118

The confidence interval :

phat ± margin of error

Margin of Error = Zcritical * √phat(1 -phat) / n

Zcritical at 95% = 1.96

Margin of Error = 1.96 * √0.29(0.71) / 118

Margin of error = 1.96 * 0.0417721

Margin of Error = 0.0818734

Confidence interval :

Lower boundary : 0.29 - 0.0818734 = 0.208

Upper boundary = 0.29 + 0.0818734 = 0.372

(0.208 ; 0.372)

We can be 95% confident that the proportion of adults with high blood pressure is lies within the interval (0.208 ; 0.372)

What is permutation?

"It is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters."

Formula of permutation:

The number of ways of obtaining an ordered set of 'r' elements from a set of 'n' elements.

[tex]^{n}P_r=\frac{n!}{(n-r)!}[/tex]

For given example,

there are 20 students in a homeroom

⇒ n = 20

Students can be elected president, vice president, treasurer and secretary.

⇒ r = 4

So, using the formula of permutation, the number of different ways they  can be chosen to be elected president, vice president, treasurer and secretary would be,

[tex]\Rightarrow ^{n}P_r=\frac{n!}{(n-r)!} \\\\\Rightarrow ^{20}P_4=\frac{20!}{(20-4)!} \\\\\Rightarrow ^{20}P_4=\bold{116280}[/tex]

Therefore, these 20 students can be chosen in 116280 different ways to be elected as president, vice president, treasurer and secretary.
