Answer 2

Answer:

x=−2 and y=−5

Step-by-step explanation:

Solve3x−2y=4for x:

3x−2y=4

3x−2y+2y=4+2y(Add 2y to both sides)

3x=2y+4

3x /3 = 2y+4 /3 (Divide both sides by 3)

x= 2 /3 y+ 4 /3

Substitute  2 /3 y+ 4 /3 for x in6x−2y=−2:

6x−2y=−2

6( 2 /3 y+ 4 /3 )−2y=−2

2y+8=−2(Simplify both sides of the equation)

2y+8+−8=−2+−8(Add -8 to both sides)

2y=−10

2y /2 = −10 /2 (Divide both sides by 2)

y=−5

Substitute−5 for y in x=

2 /3 y+ 4 /3 :

x= 2 /3 y+ 4 /3

x= 2 /3 (−5)+ 4 /3

x=−2(Simplify both sides of the equation)

uppose you have purchased a filling machine for candy bags that is supposed to fill each bag with 16 oz of candy. Assume that the weights of filled bags are approximately normally distributed. A random sample of 10 bags yields the following data (in oz): 15.87, 16.02, 15.78, 15.83, 15.69, 15.81, 16.04, 15.81, 15.92, 16.10 On the basis of this data, can you conclude that the mean fill weight is actually less than 16 oz? Let LaTeX: \alpha=5\%α = 5 %. What would be the appropriate null and alternative hypothesis?

Answers

Answer:

Null, H0: μ ≥ 16

Alternative ; H1: μ < 16

reject H0

Step-by-step explanation:

Null, H0: μ ≥ 16

Alternative ; H1: μ < 16

To compute the test statistic :

We need the sample mean and sample standard deviation :

15.87, 16.02, 15.78, 15.83, 15.69, 15.81, 16.04, 15.81, 15.92, 16.10

Using calculator :

Sample mean, m = 15.887

Standard deviation = 0.13

Test statistic :

(m - μ) / s/sqrt(n)

(15.887 - 16) / 0.13/sqrt(10)

-0.113 / 0.0411096

= - 2.749

Tcritical at 95%

Tn-1, 0.025

T10,0.025 = 2.262

Since the test statistic value is less than the critical value, reject H0

Answers

Answer:

6

Step-by-step explanation:

You first have to choose from Wide and Narrow.

Let's call them W and N

Then you have to choose 3 different pen colors.

Let call them, 1, 2, 3

So There are two choices from W and N.

Then we pick the number: 1, 2, 3.

so If you pick W, you will have 3 choices. Same for N.

So in total: 6 choices.

W= 3 choices, W1, W2, W3

N= 3 choices, N1, N2, N3

so 6 in total.

Which exponential equation is equivalent to this logarithmic equation? logx 5 + logx 12 = 7

Answers

Answer:

x^7 = 60

Step-by-step explanation:

log(a)+log(b)=log(ab) so

logx 5 + logx 12 = logx (5*12) = logx 60

logx a = b means x^b = a so x^7 = 60

The logarithm equation in exponential form is x⁷ = 60

What is an Exponential Equation?

An exponential equation that can be represented in the form of abˣ.

The logarithm equation is:

logₓ 5 + logₓ 12 = 7

According to the rule of the logarithm,

log a + log b = log (ab)

logₓ ( 5 *12) = 7

logₓ ( 60) =7

According to the property of logarithm

logₓ ( a) = b

xᵇ = a

x⁷ = 60

Write an equation in point slope form for this line THIS IS THE ANSWER, I GOT A 90%Describe the economic and political factors that caused World War II. One political factor that caused World War II was the Treaty of Versailles. The Treaty of Versailles created political tension between countries, as some provisions that were outlined within the treaty were unfair towards some of the parties involved. Take Italy for example; thousands of Italians had died in the war, but Italy was not given the land and reparations they were promised. This led to a rise in nationalism, and more Italians feeling resentment towards the Triple Entente for their abundant debt and little assistance. This is also an economic factor that caused World War II, as the aftermath of World War II left Italy in ruins, both literally and financially, and made it so that they desperately needed hope. This, in turn, led to Benito Mussolini coming into power, boasting promises of a greater Italy in the near future. Similarly, the Treaty of Versailles left Germany in a lot of debt, and many German citizens were suffering. Hitler, a charismatic leader who took advantage of the political and economic turmoil, took over and gave Germany an excuse for their problems: the Jewish population. Another economic factor that caused World War II was the worldwide depression, which put a lot of countries in a very bad position. Also, the rise of fascism and totalitarianism definitely contributed to the way World War II started, as many of the agitators of the war were in the Axis powers, and were under totalitarian dictators. then we can walk 1/3 miles in 5 minutes if Tammy walks a constant Pace how far does he walk in 1 minute What is the classification of the angle shown??A. acuteB. rightC. straightD. obtuse
