Answer:

10 students were taking science and art at the same time.

Step-by-step explanation:

Given that a group of 80 students were asked if they were taking science or art, of which 10 were taking neither, 50 were taking science, and 30 were taking art, to determine how many students take both science and art, the following calculation must be done:

80 - 10 = 70

50 - 30 - 70 = X

80 - 70 = X

10 = X

Therefore, 10 students were taking science and art at the same time.

Answer:

a] Radius of circle = 10 feet

Circumference of circle = 94.2 feet (Approx.)

Area of circle = 314 feet² (Approx.)

b] Radius of circle = 6 cm

Circumference of circle = 37.68 cm (Approx.)

Area of circle = 113.04 cm² (Approx.)

Step-by-step explanation:

Given:

a] Radius of circle = 10 feet

b] Radius of circle = 6 cm

Find:

Circumference an area for both circle

Computation:

Circumference of circle = 2πr

Area of circle = πr²

a] Radius of circle = 10 feet

Circumference of circle = 2(3.14)(10)

Circumference of circle = 94.2 feet (Approx.)

Area of circle = (3.14)(10)²

Area of circle = 314 feet² (Approx.)

b] Radius of circle = 6 cm

Circumference of circle = 2(3.14)(6)

Circumference of circle = 37.68 cm (Approx.)

Area of circle = (3.14)(6)²

Area of circle = 113.04 cm² (Approx.)

Answer:

[tex](a)\ P(x \ge 215)[/tex]

[tex](b)\ P(x \ge 214.5) = 0.07353[/tex]

Step-by-step explanation:

Given

[tex]p = 0.50[/tex] ---- proportion of watches with defects

[tex]n = 400[/tex] --- Number of watches

Solving (a): Represent at least 215 of 400 are defective

In inequalities, at least means: [tex]\ge[/tex]

So, the probability is represented as: [tex]P(x \ge 215)[/tex]

Solving (b): Calculate [tex]P(x \ge 215)[/tex]

Normal or Poisson: Normal distribution is characterized by 2 parameters [tex]\mu[/tex] and [tex]\sigma[/tex].

These two parameters can be easily calculated from the given parameters in the question. So, we solve using normal distribution

Start by calculating the mean

[tex]\mu =np[/tex]

[tex]\mu = 0.50 * 400[/tex]

[tex]\mu = 200[/tex]

Calculate standard deviation

[tex]\sigma = \sqrt{\mu (1 - p)[/tex]

[tex]\sigma = \sqrt{200 * (1 - 0.50)[/tex]

[tex]\sigma = \sqrt{200 * 0.50[/tex]

[tex]\sigma = \sqrt{100[/tex]

[tex]\sigma = 10[/tex]

By continuity correction, we have:

[tex]x \to x - 0.5[/tex]

[tex]x \to 215 - 0.5[/tex]

[tex]x \to 214.5[/tex]

So, we have:

[tex]P(x \ge 215) = P(x \ge 214.5)[/tex]

Calculating [tex]P(x \ge 214.5)[/tex], we have:

[tex]P(x \ge 214.5) = 1 - P(x < z)[/tex]

Calculate z score

[tex]z = \frac{x - \mu}{\sigma}[/tex]

[tex]z = \frac{214.5 - 200}{10}[/tex]

[tex]z = \frac{14.5}{10}[/tex]

[tex]z = 1.45[/tex]

So, we have:

[tex]P(x \ge 214.5) = 1 - P(x < 1.45)[/tex]

Using the z score probability table, we have:

[tex]P(x < 1.45) = 0.92647[/tex]

So, we have:

[tex]P(x \ge 214.5) = 1 - 0.92647[/tex]

[tex]P(x \ge 214.5) = 0.07353[/tex]

Answer:

  (d) {-7, -2, 11, 20}

Step-by-step explanation:

You can put the domain values into the function and evaluate to find the corresponding range values. Here, we'll do them "all at once."

  y = 3{-4, -1, 2, 5} +5

  = {-12, -3, 6, 15} +5

  = {-7, 2, 11, 20} . . . . . matches choice d

_____

To save yourself some arithmetic, you can observe that the answer choices differ in the 2nd and 4th values, so you only need to evaluate the function for x=-1 or x=5 to determine the correct answer choice.

Answer:

Hi i know im very late answering this question but i believe the correct option is: b = 2C - a

Step-by-step explanation:

I believe this is the answer because:

2C = the average of 2 test scores combined

A and B = the two scores

were trying to solve for b so what we would do to figure that out is have the average of both test scores and then subtract A which will leave you with only B. therefor the answer is B = 2C - a

Answer: 106.76yards

Step-by-step explanation:

Circumference of a circle is given as:

= 2πr

where,

π = 3.14

r = 17 yards

Circumference = 2πr

= 2 × 3.14 × 17.

= 106.76yards

Therefore, the circumference of the circle will be 106.76yards

When you deposit cash at a bank or credit union, you typically need to use a deposit slip. That's simply a slip of paper that tells the teller where to put the money. Write your name and account number on the deposit slip (deposit slips are usually available at the lobby or drive-throug).

Answer:

Solution given:

x²-12x+11=0

Comparing above equation with ax²+bx+c

we get

a=1

b=-12

c=11

By using Vieta's theorem

X1+X2=[tex] \frac{-b}{a} [/tex]=[tex] \frac{- -12}{1} [/tex]=12

again

X1X2=[tex] \frac{c}{a} [/tex]=[tex] \frac{11}{1} [/tex]=11

x1.x2=11

x1+x2=12

Answer:

The signs will be + and -

Step-by-step explanation:

Required

The signs in the parenthesis of difference of two squares

Let the expression be:

[tex](x^2 - a^2)[/tex]

Expand

[tex]x^2 - a^2 = x^2 -ax + ax - a^2[/tex]

Factorize

[tex]x^2 - a^2 = x(x -a) + a(x - a)[/tex]

Factor out x - a

[tex]x^2 - a^2 = (x +a)(x - a)[/tex]

See that the sign in front of a is + and - in the parentheses

Answer:

Answer:

B. 4

Step-by-step explanation:

∠4 is an alternate exterior angle with ∠2 because both angles are on the exterior of the lines, and lie on opposite ends on the transversal.

The angle that is an alternate exterior angle with angle 2 is angle 4.

Parallel lines are those lines that are equidistance from each other and never intersect each other.

Given that;

The figure is shown in figure.

Now,

Since, ∠4 is an alternate exterior angle with ∠2 because both angles are on the exterior of the lines, and lie on opposite ends on the transversal.

Hence, ∠4 is an alternate exterior angle with angle 2.

Thus, The angle that is an alternate exterior angle with angle 2 is angle 4.
