Answer:

Simple!

Step-by-step explanation:

The triangle is obviously a right triangle, meaning, we can use the Pythagorean Theorem to solve for x!

(The Pythagorean Theorem is where a^2=b^2+c^2, or the length of the hypotenuse (side opposite to the 90 degree angle) squared is equal to the length of one leg squared plus the other leg squared).

To put it simply:

x^2=20^2+5^2

Now to solve!

x^2=400+25\\x^2=425\\x=\sqrt{425} \\x=5\sqrt{17}

This cannot be simplified further, so that's your answer!

Hope this helps!

How to solve: 20^2+5^2=x^2, then you take the square root, therefore x=20.62

For a lower tail hypothesis test with a sample size of 10 and a .10 level of significance, the critical value of the test statis
Fynjy0 [20]

Using a t-distribution calculator, it is found that the critical value of the test statistic t is t^{\ast} = -1.383.

<h3>How to find the critical value of a t-test?</h3>
  • The critical value is found using a calculator.

The inputs are:

  • The tail.
  • The amount of degrees of freedom, which is one less than the sample size.
  • The significance level.

In this problem, we have a<u> lower(left-tailed) test, with 10 - 1 = 9 df and a level of significance of 0.1</u>, hence the critical value is t^{\ast} = -1.383.

How can you write an equation of a line when you are given the slope and the y-intercept of the line? Explain
tester [92]

Answer:

The linear equation that represents each function is y=mx+b. While The m represent the slop so instead of writing you write the slope provided. Then multiply by the X + b which is your Y-intercept.

Here is an example,

The slope is 2/3 and the y intercept is 6, write a linear equation for this sequence.

y= (2/3). X +6

A 7-year lease for office space states that the annual rent is $85,000 for the first year and will increase by 6% each additiona
melamori03 [73]

Answer: the total rent expense be for the entire 7-year lease is $713476

Step-by-step explanation:

The rate at which the rent increases each year is in geometric progression. The formula for determining the sum of n terms, Sn of a geometric sequence is expressed as

Sn = (ar^n - 1)/(r - 1)

Where

n represents the number of term(years) in the sequence.

a represents the first term in the sequence.

r represents the common ratio.

From the information given,

a = $85000

r = 1 + 6/100 = 1.06

n = 7

Therefore, the sum of the first 7 terms(7 year lease), S7 is

S7 = (85000 × 1.06^(7) - 1)/1.06 - 1

S7 = (85000 × 1.06^(7) - 1)/0.06

S7 = 42808.57/0.06

S7 = $713476
