The Browns scored 13 more points than the Saints. The total of

their scores was 47. How many points did each team score?

Answers

Answer:

Saints team scores points = 17

Browns team scores point = 30

Step-by-step explanation:

Let Saints team scores points = x

      Browns team scores point = y

As given,

The Browns scored 13 more points than the Saints.

⇒ y = x + 13

Now, given

The total of  their scores was 47.

⇒ x + y = 47

⇒x + x + 13 = 47

⇒ 2x = 47 - 13

⇒2x = 34

⇒x= [tex]\frac{34}{2}[/tex] = 17

∴ we get

Saints team scores points = x = 17

Browns team scores point = y = x + 13 = 17 + 13 = 30

Answer:

30 , 17

Step-by-step explanation:

browns  have x + 13

saints have y

x+13 + x+y = 47

2x = 34

x=17

17 + y = 47

y=30

Two functions are defined by these equations: f(x) = 5.1 + 0.8x g(x) = 3.4 + 1.2x Which function has a greater value when x is 3.9? How much greater?

Answers

Step-by-step explanation:

Two functions are defined by these equations:

f(x) = 5.1 + 0.8x

g(x) = 3.4 + 1.2x

Put x = 3.9 in both f(x) and g(x).

f(x) = 5.1 + 0.8(3.9)

= 8.22

g(x) = 3.4 + 1.2(3.9)

= 8.08

So, f(x) is greater than g(x).

f(x)-g(x) = 8.22 - 8.08

= 0.14

So, f(x) is 0.14 units more than g(x).

A right triangle has one leg that is 4 more than twice the other. The area of the triangle is 35. Find the length of the sides.

Answers

Answer:

one leg = 5

other leg = 14

Step-by-step explanation:

let 'x' = length of shorter leg

let '2x + 4' = length of longer leg

A = 1/2bh

35 = 1/2x · 2x + 4

35 = x² + 4

x² + 4 - 35 = 0

(x + 7)(x - 5) = 0

x = -7 and x = 5

We can eliminate -7 as an answer since a length cannot be negative

Answer:

The shorter leg = 5

The longer leg = 14

The hypotenuse = 14.866.....

Step-by-step explanation:

if we represent the smaller leg as "x" we firstly represent the longer leg as...

Longer leg = 2x + 4

(We can do this based on the question)

Now we need to undersstadn t in a right angle triangle the legs can be used as a height and base. So we can make the following equation.

[tex]A_{triangle} = \frac{bh}{2}[/tex]

Substitute the lengths of the legs as based and height and get...

[tex]A_{triangle} = \frac{(2x + 4)(x)}{2}[/tex]

[tex]35 = \frac{2x^{2} + 4x}{2}[/tex]

[tex]35 = x^{2} + 2x[/tex]

[tex]35 = x(x + 2)[/tex]

From here we can see that x = 5.

Therefore the lengths are as follows...

The shorter leg = x = 5

The longer leg = 2(5) + 4 = 14

The hypotenuse = [tex]\sqrt{5^{2} + 14^{2} }[/tex]

The hypotenuse = [tex]\sqrt{5^{2} +14^{2} }[/tex]

The hypotenuse = 14.866.....

For the following exercise, determine the range (possible values) of the random variable, X. A batch of 300 machined parts contains 10 that do not conform to customer requirements. The random variable is the number of parts in a sample of 5 parts that do not conform to customer requirements. Choose the correct answer.

a. The range of X is {0,1,2,3,4,5,6}
b. The range of X is {0,1,2,3,4,5,6}
c. The range of X is {0,1,2,3,4,5,6}
d. The range of X is {0,1,2,3,4,5,6}
e. The range of X is {0,1,2,3,4,5,6}

Answers

Answer:

{0,1,2,3,4,5}

Step-by-step explanation:

We are given that

Total number of  machine parts=300

Number of defective machine parts=10

Total number of good machine parts=300-10=290

Sample contain parts that do not conform to customer requirement=5

X  is a random variable which is the number of parts in a sample of 5 parts that do not conform to customer requirements.

We have to find the correct answer.

The sample contain 5 parts

Therefore, the possible values of random variable X

0,1,2,3,4,5

Hence, the range of X is given by

7. Washcloths were selling for $1.88 each. If 14 1/4 dozen cloths were sold, what was the retail value of the total sales

Answers

Answer:

The retail value of the total sales was $311.48

Step-by-step explanation:

14 1/4 dozen cloths were sold

This means that the total number of cloths sold was:

[tex]14*12 + 12*\frac{1}{4} = 168 + 3 = 171[/tex]

Each for $1.88

So the retail value of total sales was.

$1.88*171 = $311.48

The retail value of the total sales was $311.48

In a MBS first year class, there are three sections each including 20 students. In the first section, there are 10 boys and 10 girls, in the second section there are 15 boys and 5 girls, and in the third section, there are 12 boys and 8 girls. Five students are selected at random from each group to form committee of 15 students. What is the probability that all the 15 students selected are girls?​

Answers

Answer:

[tex]3.52 \times 10^{-9} = 3.52 \times 10^{-7}\%[/tex] probability that all the 15 students selected are girls

Step-by-step explanation:

The selection is from a sample without replacement, so we use the hypergeometric distribution to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

All girls from the first group:

20 students, so [tex]N = 20[/tex]

10 girls, so [tex]k = 10[/tex]

5 students will be selected, so [tex]n = 5[/tex]

We want all of them to be girls, so we find P(X = 5).

[tex]P_1 = P(X = 5) = h(5,20,5,10) = \frac{C_{10,5}*C_{10,5}}{C_{20,5}} = 0.0163[/tex]

All girls from the second group:

20 students, so [tex]N = 20[/tex]

5 girls, so [tex]k = 5[/tex]

5 students will be selected, so [tex]n = 5[/tex]

We want all of them to be girls, so we find P(X = 5).

[tex]P_2 = P(X = 5) = h(5,20,5,5) = \frac{C_{5,5}*C_{15,5}}{C_{20,5}} = 0.00006[/tex]

All girls from the third group:

20 students, so [tex]N = 20[/tex]

8 girls, so [tex]k = 8[/tex]

5 students will be selected, so [tex]n = 5[/tex]

We want all of them to be girls, so we find P(X = 5).

[tex]P_3 = P(X = 5) = h(5,20,5,8) = \frac{C_{8,5}*C_{12,5}}{C_{20,5}} = 0.0036[/tex]

All 15 students are girls:

Groups are independent, so we multiply the probabilities:

[tex]P = P_1*P_2*P_3 = 0.0163*0.00006*0.0036 = 3.52 \times 10^{-9}[/tex]

[tex]3.52 \times 10^{-9} = 3.52 \times 10^{-7}\%[/tex] probability that all the 15 students selected are girls

Answer:

B. x = 8√3 ≈ 13.86; y = 8

Step-by-step explanation:

✔️Find x using trigonometric ratio:

Reference angle = 60°

opposite = x

Hypotenuse = 16

Thus:

Sin(60) = x/16

16*sin(60) = x

16*√3/2 = x

8√2 = x

x = 8√3 ≈ 13.86

✔️Find y using Pythagorean Theorem:

y² = 16² - (8√3)²

y² = 256 - 192 = 64

y = √64

The perimeter of an equilateral triangle is 114mm.
State the length of one of its sides

Answers

Answer:

Since an equilateral triangle has all three side equal then one of its side is 38mm

The length of one of the sides of the triangle is 38 mm.

What is Perimeter?

The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.

Given that all of the sides of an equilateral triangle are equal in length, we may calculate the length of a side by dividing the perimeter by the triangle's total number of sides, which is 3.

As a result, the equilateral triangle's one side has the following length:

114 mm / 3 = 38 mm

Therefore, the equilateral triangle's sides are each 38 mm long.
