Answer:

Option 1 - Division Property of Equality

Step-by-step explanation:

Given : If  4x=20, then x=5.

To find : Which property justifies this statement?

Solution :

The equation is  4x=20

To make variable separate we have to remove 4 which is in multiple of variable x.

So, We divide both side by 4,

Applying division property of equality,

We can divide both sides of an equation by the same number and preserve equality.

\frac{4x}{4}=\frac{20}{4}

x=5

Therefore, The property justifies the statement is 'Division Property of Equality'.

So, Option 1 is correct.

Suppose the contact rate for a phone survey is 78% and that 22% of people will participate in that survey. Assume that agreeing
Gnoma [55]
Remember that, for independent events, the probability that both occurr is the product of the individual probabilities.

a) Probability of being contacted: 78% = 0.78

Probaility of refusing: 1 - 22% = 1 -0.22 = 0.78

Combined probability: 0.78*0.78 = 0.6084

b) The probability of failing to contact or making contact and not geeting them to agree 1 - the probability of contacting and getting them to agree.

The probabilityof contacting and getting them to agree is 0.78*0.22 = 0.1716

The the answer to this question is 1 - 0.1716 = 0.8284

Help plz!! The function h(t)=-16t^2+22t+4 models the height (h) of a football t seconds after it is thrown. The question ask to
Black_prince [1.1K]
If you're familiar with the quadratic equation
\frac{ -b \pm \sqrt{b^2-4ac}}{2a}

well, \frac{ -b}{2a} is the x component of the vertex, in your case, the vertex is the highest point

figure out what t is at the highest point, and then substitute that back into the equation in order to determine height

A train leaves boston and travels toward its destination at a speed of 60 mph. One hour later, an express train leaves Boston an
Margarita [4]

Taking into account the supplied speeds, Boston is from the destination to:

  • 240 miles

<h3>Calculation of the distance between Boston and Place of Destination</h3>

To identify the distance between Boston and the destination of the trains, it must be remembered that the <u>speed</u> mentioned for each one is a reference to the distance traveled per hour, therefore, after each hour, each train will travel :

  • Regular train: 60 miles
  • Express train: 80 miles

According to the information given, when the express train leaves, the regular train has a 60-mile lead, which is getting shorter hour by hour because the express train travels 20 miles per hour more than the normal train.

Therefore, in <u>three hours</u>, the express train would catch up with the regular train, calculating the distance thanks to the speed formula:

  • Speed =\frac{Distance}{Time}

And clearing the distance:

  • Distance=Speed*Time
  • Distance=80\frac{miles}{hour}*3hours
  • Distance=240miles

Therefore, the destination would be <u>240 miles</u> from Boston, which would take four hours by regular train and three hours by express train.
