Actual distance between two places is 130 miles. The scale of the map is

Lynna [10]

Answer:

1.3 inches

Step-by-step explanation:

1. Determine what you already know in order to set up the equation:

1 inch = 100 miles

x inches = 130 miles

Solving for x

2. Set up the equation so both numerators are the same unit (In this case, both numerators are the mile values and both denominators are the inch values.)

$\frac{100}{1}$ = $\frac{130}{x}$

3. Cross multiply (Multiply the first fraction's numerator by the second fraction's denominator, and vice versa. It doesn't matter which number is on which side of the = sign.)

100x = 130

4. Divide each side by 100 to isolate the variable.

x = 1.3

HELP!!!!!!!!

zhannawk [14.2K]

ANSWER

(Choice A)

-4(3e+4)

EXPLANATION

The given expression is

$- 7 + 3( - 4e - 3)$

We expand to get:

$- 7 - 12e - 9$

We regroup the terms to get:

$- 12e - 9 - 7$

Simplify now to get:

$- 12e - 16$

We now factor -4 to obtain:

$- 4(3e + 4)$

The correct choice is A.

Which measure is of an angle that is coterminal with a 425 degree angle

Karo-lina-s [1.5K]

We know that co terminal angles are those angles which have a difference equal to a multiple of 360 degrees. For example co terminal angle of 45 degrees is 76 degrees because their difference is equal to 720 degrees, which is a multiple of 360.

We have been given an angle 425 degrees.

From the given choices, we need to check if angles being added or subtracted to 425 degrees are multiples of 360 or not.

Let us check each of the options one by one.

(A) The angle being subtracted is $1000n$ . Therefore, we have $\frac{1000n}{360}=2.77n$ , which is not an integer for all values of n. Therefore, angle given in this option is not a co terminate angle to 425 degrees.

(B)

The angle being subtracted is $840n$ . Therefore, we have $\frac{840n}{360}=2.33n$ , which is not an integer for all values of n. Therefore, angle given in this option is not a co terminate angle to 425 degrees.

(C)

The angle being added is $960n$ . Therefore, we have $\frac{960n}{360}=2.67n$ , which is not an integer for all values of n. Therefore, angle given in this option is not a co terminate angle to 425 degrees.

(D)

The angle being added is $1440n$ . Therefore, we have $\frac{1440n}{360}=4n$ , which is an integer for all values of n. Therefore, angle given in this option is indeed a co terminate angle to 425 degrees.

Hence, correct answer is option (D).

An insurance company sets up a statistical test with a null hypothesis that the average time for processing a claim is 7 days, a

JulsSmile [24]

Answer:

There was no error

Step-by-step explanation:

There are two types of statistical errors, the type 1 error and the type 2 error. In this case we refute the null hypothesis when the hypothesis is, in fact, false, because the mean process is 9 days instead of 7. Therefore we made no errors.

If the null hypothesis were True, a type 1 error would have ocurred. If the null hypothesis were false and we didnt refute it, then a type 2 error would have ocurred.

5. determine which ordered pair is a solution of y=x+2/5

AleksandrR [38]

Well, I believe one ordered pair that is a solution to the equation would be P(3,1). Since by plugging in the X and y values into the equation the left hand side is equal to the right hand side.

Y = X + 2/5
1 = 3+2/5
1 = 5/5
1 = 1.
