Answer:

-10

Step-by-step explanation

-26 x 2 3/5 = -10

-10 x 2 = -20

3/5 of -10 is -6

-20 - 6 = -26

The number is 10.

An equation is a mathematical statement that is formed when two algebraic expressions are equated using an equal sign.

Let the number is n,

The equation formed from the statement is

(2 3/5 ) * n = -26

(13/5 ) * n =26

n = 26 * 5 / 13

n = 10

Answer:

x = 6, -8

Step-by-step explanation:

If (x - 6)(x + 8) = 0, that would imply that either (x - 6) or (x + 8) would equal zero. Using this, we can find that solving the two equations:

x - 6 = 0

and

x + 8 = 0

would yield the two solutions to the equation.

x - 6 = 0

Add 6 to both sides of the equation.

x = 6

So one of the solutions would be x = 6.

x + 8 = 0

Subtract 8 from both sides of the equation.

x = -8

So the other solution would be x = -8.

The two solutions are x = 6 and x = -8.

Answer:

y = 17x + 1

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m = slope

b = y-intercept

Answer:

y=17x+1

Step-by-step explanation:

When a question asks us to give the equation of a line, we usually organize it into this formula:

y=mx+b

This formula is called slope-intercept form. Here's what the variables mean:

y=the y-axis

m=the slope

x=the x-axis

b=the point on the line that crosses the y-axis (the y-intercept)

So to write an equation of a line with a slope of 17 and a y-intercept of 1, we would need to plug those values in as m and b.

y=17x+1

Step-by-step explanation:

In order to find what two numbers [tex]\sqrt{56}[/tex] is between, we need to find two numbers that, when squared, get us close to 56.

Let's see. We know that [tex]7^2 = 49[/tex]. We also know that [tex]8^2 = 64[/tex]

We know that 56 is in between 7 and 8's squares - 49 and 64. This means that [tex]\sqrt{56}[/tex] will be in between [tex]7^2[/tex] and [tex]8^2[/tex].

Answer:

m∠1= 110

m∠2= 39

m∠3= 31

Step-by-step explanation:

All of these angles would sum up to 360 degrees, but due to half of the angles missing, then we can only do half at a time.

First, the angles given are m∠4, m∠5, and m∠6. Which are:

m∠4= 90

m∠5= 59

m∠6= 31

So, we need to find m∠1. To do so, the equation would be: m∠5+m∠6+m∠1= 180

Step 1- Substitute into the equation with the information given.

59+31+m∠1= 180

Step 2- Simplify.

90+m∠1= 180

Step 3- Subtract 90 to both sides.

90+m∠1= 180

-90              -90

m∠1= 110

So, now we know m∠1 which is 110 degrees.

Now, for m∠2 the equation would be: m∠1+m∠2+m∠6= 180

Substitute into the equation.

110+m∠2+31= 180

Step 1- Add to simplify,

141+m∠2= 180

Step 2- Subtract 141 to both sides.

141+m∠2= 180

-141              -141

m∠2= 39

Now we know most of them, and now we need m∠3.

The equation would be: m∠1+m∠2+m∠3= 180

Substitute the equation with the information given.

110+39+m∠3= 180

Step 1- Add to simplify.

149+m∠3= 180

Step 2- Subtract 149 to both sides.

149+m∠3= 180

-149             -149

m∠3= 31

Now we know all the angles!

Answer:

The probability that the selected review was submitted in Word format is 0.56.

Step-by-step explanation:

We are given that Data on recent reviews indicates that 50% of them are short, 30% are medium, and the other 20% are long. Reviews are submitted in either Word or LaTeX. For short reviews, 70% are in Word, whereas 50% of medium reviews are in Word and 30% of long reviews are in Word.

Let the probability that there are short reviews = P(S) = 0.50

The probability that there are medium reviews = P(M) = 0.30

The probability that there are long reviews = P(L) = 0.20

Let W = event that the reviews are submitted in either Word or LaTeX

So, the probability that short reviews are submitted in Word = P(W/S) = 0.70

The probability that medium reviews are submitted in Word = P(W/M) = 0.50

The probability that long reviews are submitted in Word = P(W/L) = 0.30

(a) The probability that the selected review was submitted in Word format is given by = P(W)

    P(W) = P(S) [tex]\times[/tex] P(W/S) + P(M) [tex]\times[/tex] P(W/M) + P(L) [tex]\times[/tex] P(W/L)  

             = (0.50 [tex]\times[/tex] 0.70) + (0.30 [tex]\times[/tex] 0.50) + (0.20 [tex]\times[/tex] 0.30)

             = 0.35 + 0.15 + 0.06

             = 0.56

Hence, the probability that the selected review was submitted in Word format is 0.56.

(b) Now, if the selected review was submitted in Word format, the posterior probabilities of it being short is given by = P(S/W)

        P(S/W) = [tex]\frac{P(S) \times P(W/S)}{P(S) \times P(W/S)+P(M) \times P(W/M)+P(L) \times P(W/L)}[/tex]

                    = [tex]\frac{0.50\times 0.70}{0.50\times 0.70+0.30\times 0.50+0.20\times 0.30}[/tex]

                    = [tex]\frac{0.35}{0.56}[/tex] = 0.625

Similarly, if the selected review was submitted in Word format, the posterior probabilities of it being medium is given by = P(M/W)

        P(M/W) = [tex]\frac{P(M) \times P(W/M)}{P(S) \times P(W/S)+P(M) \times P(W/M)+P(L) \times P(W/L)}[/tex]

                     = [tex]\frac{0.30\times 0.50}{0.50\times 0.70+0.30\times 0.50+0.20\times 0.30}[/tex]

                     = [tex]\frac{0.15}{0.56}[/tex] = 0.268

Also, if the selected review was submitted in Word format, the posterior probabilities of it being long is given by = P(L/W)

        P(L/W) = [tex]\frac{P(L) \times P(W/L)}{P(S) \times P(W/S)+P(M) \times P(W/M)+P(L) \times P(W/L)}[/tex]

                     = [tex]\frac{0.20\times 0.30}{0.50\times 0.70+0.30\times 0.50+0.20\times 0.30}[/tex]

                     = [tex]\frac{0.06}{0.56}[/tex] = 0.107.

Step-by-step explanation:

Credit cards can be safer than cash because of: c. If a merchant does not hold up their end of an agreement, you can call the credit company and dispute the charges

Credit card is a small plastic payment card issued by an individual's bank, which allows the owner of the card to pay a merchant for goods and services, based on the accrued debt of the card owner.

In case a merchant doesn't keep up with an agreement, to be on a safer side, a cardholder can contact the credit company to settle the disputed charges.
