Answers

Answer:

x² - 6x = -5

x = {1, 5}

Step-by-step explanation:

The square of a number minus six times a number equals negative five.

x² - 6x = -5

Add 5 to both sides

x² - 6x + 5 = 0

Factor

(x - 1)(x - 5) = 0

x = {1, 5}

Answer:

[tex]x^{2} - 6x = -5[/tex]

x = 1 or x = 5

Step-by-step explanation:

Let x = the no.

[tex]x^{2} - 6x = -5\\x^{2} - 6x + 5 = 0[/tex]

(x - 1)(x - 5) = 0

x = 1 or x = 5

Answer:

94

Step-by-step explanation:

So

376= x + 3x

Where x is the hambugers and 3 x is cheeseburgers

so it is the same as

376= 4x

divide both sides by 4

x= 94

we can check by tripling x = 283 and adding the hamburgers we found to be 94 which gives us 376

A bag contains 7 red cubes, 3 yellow cubes, 2 green cubes, and 4 blue cubes, one cube is selectef at random from the bag. What is the probability that the seleceted cube will not be blue.

Answers

The answer is 12/16 because there’s 4 blue cubes and 16 cubes total .

The probability that the selected cube will not be blue is given as;

P(selected cube not blue) = 3/4

We are given that;

Number of red cubes = 7 cubes

Number of yellow cubes = 3 cubes

Number of green cubes = 2 cubes

Number of blue cubes = 4 cubes

Total number of cubes = 7 + 3 + 2 + 4

Total number of cubes = 16 cubes

Probability that the cube that is selected is blue;

P(selected cube is blue) = 4/16 = 1/4

Thus, probability that it will not be blue will be;

P(selected cube not blue) = 1 - (1/4)

P(selected cube not blue) = 3/4

The probability that a birth will result in twins is 0.017. Assuming independence​ (perhaps not a valid​ assumption), what is the probability that out of 120 births in a​ hospital, there will be exactly 4 sets of​ twins?


The probability that there will be exactly 4 sets of twins is?

Answers

Answer:

0.0939 = 9.39% probability that there will be exactly 4 sets of twins.

Step-by-step explanation:

For each birth, there is only two possible outcomes. Either it results in twins, or it does not. The probability of a birth resulting in twins is independent of any other birth. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [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]

And p is the probability of X happening.

The probability that a birth will result in twins is 0.017.

This means that [tex]p = 0.017[/tex]

120 births:

This means that [tex]n = 120[/tex]

The probability that there will be exactly 4 sets of twins is?

This is P(X = 4).

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 4) = C_{120,4}.(0.017)^{4}.(0.983)^{116} = 0.0939[/tex]

0.0939 = 9.39% probability that there will be exactly 4 sets of twins.

Anna wants to buy 4 sweaters. The sweater come at a discount rate. If you buy one sweater regular price the other sweater is 40% off. How much percent is off of each sweater?

Answers

Answer:

20%

------------------------

If you buy a sweater, the second one is at 40% discount.

Divide the discount between the two to get:

40%/2 = 20%

You get a discount of 20% for each sweater.

Answer:

Discount percentage = 20%

Step-by-step explanation:

Discount of the sweaters,

→ first sweater = 0%

→ other sweater = 40%

The average discount percent is,

→ (first sweater + other sweater)/2

→ (0% + 40%) ÷ 2

→ (0 + 40)/2

→ 40/2

→ 20% off

Hence, the answer is 20% off.

17v = 62 (exponential equations with logarithms, solve)

Answers

Therefore v = log(62) / log(17) is the solution for v, the unknown variable in the equation.

Define log(Logarithm).

The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent to which b must be increased in order to obtain a number x is the logarithm of x to the base b.  For example, since 1000 = 10³, the logarithm base 10 of 1000 is 3, or log₁₀ = 3.

What is a function?

A function in mathematics is an expression, rule, or law that establishes the connection between an independent variable and a dependent variable (the dependent variable). Each element of X receives precisely one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.

To solve this exponential equation, we can use the logarithms property that is log(a^b) = b*log(a).

Given the equation 17v = 62, we can take the logarithm base 17 of both sides:

log(17^v) = log(62)

v*log(17) = log(62)

Dividing both sides by log(17) gives us:

v = log(62) / log(17)

This is the solution for v, the unknown variable in the equation.

How many sides does a regular polygon have if one interior angle measures 144°

Answers

Answer: 10 sides

Step-by-step explanation:

You can always use the given formula to calculate but I (personally) find it much easier to calculate the number of sides using the exterior angle.

To calculate the exterior angle, it is 180 - the interior angle.

In this example, the exterior angle would be 180-144 = 36°

Because it is a regular polygon, we know that all the angles in the shape are the same.

In all polygons, the exterior angles always add up to 360 degrees.

So divide 360 by 36 (the size of each exterior angle), and you get 10.

360/36 = 10

Given the parabola is opening downward, the function has to be negative. Therefore, A B and D are correct.

The following equations could define the given quadratic function.

1. -1(x-1)²+9

4. -x²+2x+8

What is Parabola?

A parabola is a U-shaped curve this is drawn for a quadratic function,

f(x) = ax² + b x + c.

1. The function -1(x-1)²+9 represents a downward-facing parabola.

The vertex of the parabola is at point (1, 9), and it opens downward because the coefficient of the squared term (-1) is negative.

4. The function -x²+2x+8 represents a downward-facing parabola as well.

6. The parabola intersects the x-axis at x = -2 and x = 4.

Hence, the correct answer is options 1, 4, 6.

Prove that for any natural n: a the number 7^(n+4) −7^n is divisible by 30.

Answers

For, n = 0, 1 we proved that 7⁽ⁿ⁺⁴⁾ - 7ⁿ hence by induction it is divisible by 30 for all n ∈ N.

What is mathematical induction?

An inductive proof requires two cases. The first, or base case, establishes the proposition that n = 0 without requiring any prior knowledge of other situations. The second example, the induction step, demonstrates that if the assertion is true for any particular case where n = k, then it must also be true for the subsequent case when n = k + 1. These two actions prove that the statement is true for all n = 1 natural numbers. The base case establishes the truth of the statement for all natural numbers n N, but it does not always start with n = 0. Instead, it frequently starts with n = 1, and it may also start with any fixed natural number n = N.

Given, We have to prove 7⁽ⁿ⁺⁴⁾ - 7ⁿ is divisible by 30 for all n ∈ N.

Let, n = 0.

Therefore,

7⁴ - 7⁰.

= 2401 - 1.

= 2400.

= 30×80, Divisible by 30.

Similarly for n = 1 we have,

7⁵ - 7¹.

= 16807 - 7.

= 16800.

= 30×560.

Hence by induction, the cycle will continue.
