what is the distance between (7, -7) and (9,-9)

An equation is formed of two equal expressions. The value of x is the equation ax-b=c is (c+b)/(a).

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution of x in the given equation can be written as,

[tex]ax - b = c\\\\ax = c+b\\\\x = \dfrac{c+b}{a}[/tex]

Hence, the value of x is the equation ax-b=c is (c+b)/(a).

Answer:

m∠XWY = 70°

Explanation:

Two opposite interior angle sum up to one exterior angle on a straight line.

============

? + 45° = 115°

? = 115° - 45°

? = 70°

Answer:

The value of angle XWY = 70°

Step-by-step explanation:

=> angle XYZ + angle XYW = 180° { linear pair }

=> angle XYW + 115° = 180°

=> angle XYW = 180° - 115°

=> angle XYW = 65°

Now angle WXY + angle XWY + angle XYW = 180° { sum of angles of a triangle is 180° }

=> 45° + 65° + angle XWY = 180°

=> angle XWY + 110° = 180°

=> angle XWY = 180° - 110°

=> angle XWY = 70°

Answer:

B. 5/12

Explanation:

Total Letters mixed: {S, E, M, I, T, R, O, P, I, C, A, L} = 12 Letters

There are 5 vowels and they are: 'a', 'e', 'i', ' o', and 'u'

In here the vowels are: E, I, O, I, A = 5 vowels here

So,

Answer:

25/6

Step-by-step explanation:

Take the number on the left multiply by the denominator and add the numerator which is 4×6+1 =25

Reuse the same denominator which is 6 so 25/6

Work backwards: 25/6 to 4 1/6 (25 divide by 6 is 4 remainder 1 so 4 on the left and 1 as the numerator)

Answer:

25/6

Step-by-step explanation:

put the denominator as it is

Step-by-step explanation:

Step-by-step explanation:

The prediction for the number of passwords in which the first character is a vowel is 56 passwords.

Binomial distributions consist of n independent Bernoulli trials.

Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as

[tex]X \sim B(n,p)[/tex]

The probability that out of n trials, there'd be x successes is given by

[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]

The expected value and variance of X are:

[tex]E(X) = np\\[/tex]

Given that the characters that can be used are numbers 0 through 9 and lowercase letters. Therefore, a total of 36 different characters are available.

Since we need to know the passwords made with vowels, therefore, the probability of a password in which the first character will be a, e, i, o, u is (5/36).

Now as the computer produces 400 passwords, therefore, the predicted value can be written as,

[tex]E = np = 400 \times \dfrac{5}{36} = 55.5556 \approx 56[/tex]

Hence, the prediction for the number of passwords in which the first character is a vowel is 56 passwords.

Answer:

The distance around the outside of the track is 4183.58m².

Step-by-step explanation:

The area of running track that goes around the field is 9.76m

To proof :

Formula -

(Area of rectangle = length × breadth)

(Area of running track = outside area - inside area)

First case (outside),

length = 73 +2× 9.76

= 92.52m

Breadth = 84.39 m

radius of outside semi circle,

= 46.26m

outside area = area of rectangle + 2 × area of the semi-circle

= 92.52 x 84.39 + 3.14 x 46.26 × 46 × 26

= 7807.76+6719.56

Second case,

radius of the semi-circle,

=36.5m

inside area = area of rectangle + 2x area of the semi-circle

=73x 84.39+ 3.14x 36.5×36.5

= 6160.47 +4183.27

= 10343.74m²

Now,

Area of running track = 14527.32 m²- 10343.74m²

= 4183.58m²

The distance around the outside of track is 4183.58m².
