Dale is 35 years old and planning to retire at age 65. He will invest an average of $155 each month with an average annual retur
weeeeeb [17]
Since he is investing the same amount monthly, we have to apply annuity formula. And it is planned for the future. So that, we'll apply future value annuity formula. The formula is FV=A[ \frac{(1+ \frac{r}{s})^{Ns} -1 }{r} ], where A is the monthly payment, r is the percentage rate, s is 12 (monthly compound) and N is the time, which is 30. Plugging the numbers into the formula, we write that FV=155[ \frac{(1+ \frac{0.037}{12} )^{12*30} - 1 }{0.037}  ] = $8485.450857

Estimate the product of 67 x 23<br> by rounding to the nearest ten.
elena-14-01-66 [18.8K]

Answer:

1400

Step-by-step explanation:

67 rounds to 70 because 7 is bigger than 5 so it rounds up. 23 rounds down since 3 is smaller than 5.

So, 70x20=1400

Please help fast! Rosa's friend Jake claims that he can read minds. To test Jake's abilities, Rosa chooses 3 different numbers
grigory [225]

Jake's guesses are illustrations of probabilities.

The probability that Jake's guesses are correct is 1/720

The sample size is:

\mathbf{n = 10} --- 10 different numbers

The probability that Jake's guesses are correct is as follows:

  • 1st guess = 1/10
  • 2nd guess = 1/9
  • 3rd guess = 1/8

So, the required probability is:

\mathbf{Pr = \frac{1}{10} \times \frac 19 \times \frac 18}

\mathbf{Pr = \frac{1}{720} }

Hence, the probability that Jake's guesses are correct is 1/720

A right triangle is shown below.
Norma-Jean [14]
<h2>Answer: <em>x = 7.5</em></h2>

<em />

Step-by-step explanation:

Use the Pythagorean Theorem ( a^{2}+b^{2} =c^{2} )

The longest side is <em>c = the hypotenuse</em>, and <em>a and b = the other sides</em> of the triangle.

a = 4                              First: 4^{2}+x^{2}=8.5^{2}

b = x                         Second: 16+x^{2}=72.25  

c = 8.5                          Third: x^{2}=56.25

                                  Fourth: x=\sqrt{56.25}

                                      Fifth: x = 7.5
