What expression is equal to 7x(2+3)

Answer:

A) 3<x<5

Step-by-step explanation:

Given: |2x-8|<2

Make two inequalities:

First inequality:

2x-8<2

2x<10

x<5

Second inequality:

2x-8>-2

2x>6

x>3

Therefore, your solution is 3<x<5 since the two inequalities pass each other, making an "and" inequality.

Ur should be noted that Kathy Lehner owes approximately $1,311.97.

Previous balance (10/1): $1,164

Credit (10/3): $79 credit. This reduces the balance, so the new balance is $1,164 - $79 = $1,085.

Charge: King Soopers (10/12): $148 charge. This increases the balance, so the new balance is $1,085 + $148 = $1,233.

Payment (10/15): $310 credit. This reduces the balance, so the new balance is $1,233 - $310 = $923.

Charge: Delta (10/25): $321 charge. This increases the balance, so the new balance is $923 + $321 = $1,244.

Charge: Holiday Fun (10/30): $61 charge. This increases the balance, so the new balance is $1,244 + $61 = $1,305.

Interest calculation: $1,305 * (6% * (31/365)) = $6.9698 (rounded to the nearest cent, which is $6.97).

Finally, to determine the total amount owed, we add the balance and the interest:

Total amount owed: $1,305 + $6.97 = $1,311.97

Therefore, Kathy Lehner owes approximately $1,311.97.

Answer:

Juan:  42

Diego: 14

Step-by-step explanation:

(d - 10) + (j - 10) = 36

d + j -20 = 36

d + j = 56

j = 3d

d + 3d = 4d = 56

d = 56/4 = 14

j = 3d = 3(14) = 42

Answer:

3

Step-by-step explanation:

1 hour = 60 minutes.

1/4 of an hour = 60 minutes / 4 = 15 minutes.

15 minutes / 5 minutes segments = 3

There are 3 five-minute segments in 1/4 of an hour

Answer:

C.

Step-by-step explanation:

Answer is C. because there are a total of 60 minutes in 1 hour. We know that there is 30 minutes in half a hour. Half of 30 minutes is 15 minutes and it takes 3 five minute segments to get 15 minutes.

You can do it like this 60 * 1/4 = 60/4

60/4 = 15/1

15 = 5 * 3

Answer:

1 Which model represents 2(-3)

figure c represents  2(-3)

Step-by-step explanation:

Answer:

z(min)  = 1400

x = 3

y = 2

Step-by-step explanation:

Formulation:

Let´s call

x number of running hours of process 1

y number of running hours of process 2

Then Objective Function to minimize is:

z  =  400*x  + 100*y

Constrains:

Subject to

Demand constraint ( by type of brews)

300*x  + 100y ≥ 1000

100*x + 100*y ≥ 500

100*x ≥ 300

General constraint

y≥0     Note that we already have  x≥= (in the third constraint)

By using the on-line slver we find:

z (min) = 1400 $

x = 3

y = 2

Answer:

0.0668 = 6.68% probability that the average price change of this sample is less than 1.0.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set 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]

The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean µ = 1.1 and variance σ2 = 0.16. You collect a sample of 36 such price changes.

So the standard deviation is:

[tex]\sigma = \sqrt{\sigma^2} = \sqrt{0.16} = 0.4[/tex]

Sample of 36:

This means that [tex]s = \frac{0.4}{\sqrt{36}} = 0.0667[/tex]

Probability that the average price change of this sample is less than 1.0.

This is the pvalue of Z when X = 1. So

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

[tex]Z = \frac{1 - 1.1}{0.0667}[/tex]

[tex]Z = -1.5[/tex]

[tex]Z = -1.5[/tex] has a pvalue of 0.0668

0.0668 = 6.68% probability that the average price change of this sample is less than 1.0.

Answer:

x = 40°

Step-by-step explanation:

In order to answer this problem, you will need to know the definition of an isosceles triangle.

          An Isosceles triangle is specified as a triangle with 2 of its 3 sides having equal lengths.

Step 1: Draw your triangle.

Since 2 of your 3 sides are equal length and the primary angle measures 100°, you are dealing with an obtuse triangle or, properly named, a obtuse isosceles triangle.

Step 2: Label your angles inside of your triangle.

Remember that the sum of the angles inside of a triangle must add up to equal 180°.

Since we know the triangle we are dealing with in this problem, we can label our unknown angles 'x'.

      Caution: The above statement ONLY applies to this type of triangle.

Step 3: Write an equation.

           100° + x° + x° = 180°

Step 4: Solve for x.

           100° + x° + x° = 180°

             100° + 2x° = 180°

                 2x = 80°

                x = 40°
