[tex]\displaystyle 7x + 9y = 45[/tex]

Step-by-step explanation:

y = –⁷⁄₉x + 5

+ ⁷⁄₉x + ⁷⁄₉x

___________

⁷⁄₉x + y = 5 [We CANNOT leave the equation like this, so multiply by 9 to eradicate the fraction.]

9[⁷⁄₉x + y = 5]

[tex]\displaystyle 7x + 9y = 45[/tex]

Dan loves to compete in triathlons. At a race a few months ago, he finished in 300 minutes. Yesterday, he completed another triathlon and finished in 306 minutes. What was the percent of increase in Dan's finishing time?

Answers

Answer:

2%

Step-by-step explanation:

If 300 minutes is 100%, how much percent is 306 minutes?

we need to use the rule of three

306 minutes x 100% / 300 minutes = 102%

Therefore the percent of the increase is 102%-100%= 2%

(-8+4i)(1 - i)
Which of the following is equivalent to the complex number shown above?
Note: i = -1

Answers

Answer:

-4 + 12i

Step-by-step explanation:

(-8 + 4i) (1 − i)

Distribute using FOIL.

(-8)(1) + (-8)(-i) + (4i)(1) + (4i)(-i)

-8 + 8i + 4i − 4i²

-8 + 12i + 4

-4 + 12i

The product of two complex numbers (-8+4i) and (1 - i) is - 4(1 + i).

What is a complex number?

"A complex number is a number of the form a + bi, where 'a' and 'b' are real numbers. Here, i = √(- 1)."

Given, (- 8 + 4i)(1 - i)

= (- 8 + 4i - 8i - 4i²)

= [- 8 - 4i - 4(- 1)]

= (- 8 - 4i + 4)

= (- 4 - 4i)

= - 4(1 + i)

4 A game is being watched by 60 adults and some
children. If there are 20 more adults than children,
how many children are watching the game?
Lo Children

Answers

Answer:

20 children.

Step-by-step explanation:

We can solve this using an equation or simple mental math:

The equation: x=children x+20=adults

x + (x+20) = 60

2x + 20 = 60

2x = 40

x = 20

Mental Math: 40 plus 20 is 60 and 40 is 20 more than 20 so there are 40 adults and 20 children.

solve this 28 - x = 24​

Answers

Answer:

I

Answers

Answer:

-188, -187, -186

Step-by-step explanation:

x + (x+1) +(x+2) will usually be the formula for questions like this. If there wer 4 consecutive numbers, you just add (x+3) and so on.

The three integers are:

x + (x+1) + (x+2)   Simplify this :

3x+3 = -561       Get 3x by itself, subtract 3 on both sides:

    -3    -3

3x = -564   Find x divide -564 and 3:

x = -188

-188 is the first number now you count up.

-188 is the first number, -187 is the second, -186 is the third.

Intelligence Quotient (IQ) scores are often reported to be normally distributed with μ=100.0 and σ=15.0. A random sample of 59 people is taken. Step 1 of 2 : What is the probability of a random person on the street having an IQ score of less than 98 ? Round your answer to 4 decimal places, if necessary.

Answers

Using the normal distribution, it is found that there is a 0.4483 = 44.83% probability of a random person on the street having an IQ score of less than 98.

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem, the mean and the standard deviation are, respectively, given by [tex]\mu = 100[/tex] and [tex]\sigma = 15[/tex].

The probability of a random person on the street having an IQ score of less than 98 is the p-value of Z when X = 98, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{98 - 100}{15}[/tex]

[tex]Z = -0.13[/tex]

[tex]Z = -0.13[/tex] has a p-value of 0.4483.

0.4483 = 44.83% probability of a random person on the street having an IQ score of less than 98.
