Step-by-step explanation:

If there are 35 toy vehicles, then there will be 7 cars

(Divide) 35/5

a) The value of x is 42.6 when k =16/3 is directly proportional to y.

b) The value of x is -56 when k is -7  is directly proportional to y.

What kind of variation is one where x and y are directly proportional?

x varies directly as y

x α y

x = ky

a) x=6 ; y = 32

x = ky

6 = k(32)

k = 16/3

if y = 8

then,

x = (16/3) * 8

= 128/3

x = 42.6

Hence, the value of x is 42.6 when k =16/3 is directly proportional to y.

b) x= 14 and y = -2

x = ky

14 = k(-2)

k = -7

if y = 8

then,

x = ky

x= (-7) 8

x = -56

Hence, the value of x is -56 when k is -7  is directly proportional to y.

Answer:

  B)  15/17

Step-by-step explanation:

You want the sine of acute angle A in the right triangle shown.

The sine of the angle is the ratio ...

  Sin = Opposite/Hypotenuse

We can go to the trouble to figure the hypotenuse, or we can choose the only suitable answer from the list provided. (It is the one marked already.)

The leg lengths of the triangle shown are 8 and 15, with leg 15 being opposite angle A. This is the first clue that the ratio will have 15 in the numerator. Only answer choice B matches.

The value of the sine function is never greater than 1, eliminating answer choices A, C, and E, leaving choices B and D.

Since the side opposite angle A is the longest of the two legs, we know that angle A is more than 45°, and its sine is more than √2/2. That means choice D can be eliminated, since it is less than 1/2.

The sine of angle A is 15/17.

The value of EH is such that F is between E and G, and G is between F and H will be 12.

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

As per the given,

F is between E and G

FG = 4

Since, EG = EF + FG

9 = EF + 4

EF = 5

Given, FH = 7

EH = EF + FH

EH = 5 + 7 = 12

Answer:

a = b = 3√2

Step-by-step explanation:

Use trigonometry:

\( \sin(45°) = \frac{a}{6} \)

Cross-multiply to find a:

\(a = 6 \times \sin(45°) = 6 \times \frac{ \sqrt{2} }{2} = \frac{6 \sqrt{2} }{2} = 3 \sqrt{2} \)

Use the Pythagorean theorem to find b:

\( {b}^{2} = {6}^{2} - {a}^{2} \)

\( {b}^{2} = {6}^{2} - ( {3 \sqrt{2}) }^{2} = 36 - 9 \times 2 = 36 - 18 = 18\)

\(b > 0\)

\(b = \sqrt{18} = 3 \sqrt{2} \)

A regular polygon has equal side lengths and congruent interior angles.

The sum of the interior angles of any regular polygon is determined using the formula: (n - 2)180, where n is the number of sides.

Thus, given polygon GHIJK has 5 sides, we would have the following:

The polygon is a regular pentagon.

Sum of all its interior angles = (5 - 2)180 = 540°.

Each interior angle = 540/5 = 108°

Step-by-step explanation:

Answer:

x = - \(\frac{3}{4}\) , x = 1

Step-by-step explanation:

4x² = x + 3 ← subtract x + 3 from both sides

4x² - x - 3 = 0 ← in standard form

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 4 × - 3 = - 12 and sum = - 1

the factors are - 4 and + 3

use these factors to split the x- term

4x² - 4x + 3x - 3 = 0 ( factor the first/second and third/fourth terms )

4x(x - 1) + 3(x - 1) = 0 ← factor out (x - 1) from each term

(x - 1)(4x + 3) = 0 ← in factored form

equate each factor to zero and solve for x

4x + 3 = 0 ( subtract 3 from each side )

4x = - 3 ( divide both sides by 4 )

x = - \(\frac{3}{4}\)

x - 1 = 0 ( add 1 to both sides )

x = 1

solutions are x = - \(\frac{3}{4}\) , x = 1

We knοw that the y-intercept is -1 here we get -25a = -1, which means that a = 1/25.

We can write the pοlynοmial P(x) as:

\(P(x) = a(x-1)^2(x+5)\)

where "a" is a cοnstant cοefficient that we need tο determine.

We knοw that the y-intercept is -1, which means that P(0) = -1. Plugging in x=0, we get:

\(P(0) = a(0-1)^2(0+5) = -25a\)

Therefοre, -25a = -1, which means that a = 1/25.

Sο, the pοlynοmial P(x) is:

\(P(x) = (1/25)(x-1)^2(x+5)\)

We can see that this pοlynοmial has a multiplicity 2 rοοt at x=1 and a multiplicity 1 rοοt at x=-5, as required.

How to find equivalent fractions?

Two fractions are equivalent when they are both equal when written in the lowest terms. The fraction 18/ 20  is equal to 9/ 10   when reduced to the lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (9/ 10 ) by the same integer number, i.e., multiply by 2, 3, 4, 5, 6 ...

18/ 20  is equivalent to 9/ 10  because 9 x 2 = 18 and 10 x 2 = 20

27/ 30  is equivalent to 9/ 10   because 9 x 3 = 27 and 10 x 3 = 30

36/ 40  is equivalent to 9/ 10  because 9 x 4 = 36 and 10 x 4 = 40

and so on ...

At a glance, equivalent fractions look different, but if you reduce then to the lowest terms you will get the same value showing that they are equivalent. If a given fraction is not reduced to lowest terms, you can find other equivalent fractions by dividing both numerator and denominator by the same number.

What is an equivalent fraction? How to know if two fractions are equivalent?

Finding equivalent fractions can be ease if you use this rule:

Equivalent fractions definition: two fractions a/ b  and c/ d   are equivalent only if the product (multiplication) of the numerator (a) of the first fraction and the denominator (d) of the other fraction is equal to the product of the denominator (b) of the first fraction and the numerator (c) of the other fraction.

In other words, if you cross-multiply (a/ b  and c/ d ) the equality will remain, i.e, a.d = b.c. So, here are some examples:

18 /20  is equivalent to 9 /10  because 18 x 10 = 20 x 9 = 180

27/ 30  is equivalent to 9/ 10  because 27 x 10 = 30 x 9 = 270

36/ 40   is equivalent to 9/ 10  because 36 x 10 = 40 x 9 = 360

Find the​ mean, variance, and standard deviation of the binomial distribution with the given values of n and p. ​, The​ mean, ​, is nothing. ​(Round to the nearest tenth as​ needed.)

    p =  0.6   n =  18

Answer:

The mean   \(\mu = 10.5\)

The standard deviation \(\sigma = 2.08\)

The  variance   \(var = 4.32\)

Step-by-step explanation:

From the question we are told that

      The probability of success   is  \(p = 0.6\)

      The  sample size is \(n = 18\)

  Generally given that the distribution is binomial, then the probability of failure is mathematically represented as

              \(q = 1- p\)

substituting values

              \(q = 1- 0.6\)

              \(q =0.4\)

Generally the mean is mathematically evaluated as

             \(\mu = np\)

substituting values

             \(\mu = 18 * 0.6\)    

             \(\mu = 10.5\)

The  standard deviation is evaluated as

              \(\sigma = \sqrt{npq}\)

substituting values

               \(\sigma = \sqrt{18 * 0.6 * 0.4}\)

              \(\sigma = 2.08\)

The variance is evaluated as

               \(var = \sigma^2\)

substituting value

              \(var = 2.08^2\)

              \(var = 4.32\)

Answer:

Angle B = 106.6 degrees

Step-by-step explanation:

b^2= a^2+c^2-2*a*c*cosB

9*9 = 4*4 + 7*7 - 2*7*4*cosB

81= 16+49-56cosB           Subtract 16 and 49 from both sides

16= -56cosB           Divide by -56 on both sides.

cosB= -16/56         Take the arccosine of both sides

B=arccos(-16/56)                    

B= 106.6

Answer:

B. 106.6

Step-by-step explanation:

To solve for angle B, we can use the law of cosines.

Recall that the law of cosines states \(b^2=a^2+c^2-2ab*cos(B)\)

When this is solved for angle B, we get \(B=cos^{-1}( \frac{a^2+c^2-b^2}{2ac} )\)

In this triangle, \(a=7, b=9, c=4\)

Now, we can plug these numbers into our equation and then simplify to get B.

\(B=cos^{-1}( \frac{7^2+4^2-9^2}{2(7)(4)} )\\\\B=cos^{-1}( \frac{49+16-81}{56} )\\\\B=cos^{-1} (\frac{-16}{56} )\\\\B=106.602\\\\B=106.6\)
