10. You are asked to count the digits of the numbers in the elevation column of the table. The first number, -512, has three digits: -5, 1, and 2. The second number, -8327, has 4 digits: 8, 3, 2, and 7. You are asked to find the two numbers in the column that both have 4 digits. (Hint: -8327 is one of them.)

In the number -8,327, the digit in the thousands place is 8. (Hint: you read the number as "minus 8 thousand 3 hundred ...".) In the other 4-digit number, the digit in the thousands place is 1.

8 is greater than 1, so the number with the greater digit in the thousands place is -8327.

This number (-8327) is the elevation of the lowest place on Earth. The name of that place is found in the first column of the table where this number is in the second column. The name and number go into the last two blanks of problem 10.

_____

11. Using the method of problem 10, you find which of the numbers -52 or -92 has the largest tens digit. That's the line of the table you pick for the answer to problem 11.

HELP PLS i need this right now

Margarita [4]

Answer:

16.6

Step-by-step explanation:

By the property of intersecting secants outside of a circle, we have:

$5 \times (5 + x) = 6 \times (6 + 12) \\ 25 + 5x = 6 \times 18 \\ 25 + 5x = 108 \\ 5x = 108 - 25 \\ 5x = 83 \\ x = \frac{83}{5} \\ x = 16.6$

What are vertices of the conic 16x² - 25y² = 400 ?

garri49 [273]

Answer:

(-5, 0) and (5, 0)

Step-by-step explanation:

This equation fits the form for a hyperbola with x-intercepts. The standard form for such an equation is

$\frac{x^2}{a^2}-\frac{y^2}{b^2}=1$

To get the equation in the question into this standard form, divide each term by 400.

$\frac{16x^2}{400}-\frac{25y^2}{400}=\frac{400}{400}\\\frac{x^2}{25}-\frac{y^2}{16}=1$

To find the x-intercepts, make y = 0.

$\frac{x^2}{25}=1\\x^2=25\\x=\pm 5$

The vertices are located at the points (-5, 0) and (5, 0).

Note: There are no y-intercepts; making x = 0 produces no real solutions for y.

In the past few years, outsourcing overseas has become more frequently used than ever before by U.S. companies. However, outsour

Sliva [168]

Answer:

P(X=5)=0.1032

Step-by-step explanation:

This variable can be modeled by a binomial distribution, with parameters n=15 (sample size) and p=0.2 (the individual probability that the company use a consultant).

The probability that k companies that outsource overseas use a consultant can be written as:

$P(x=k) = \dbinom{n}{k} p^{k}(1-p)^{n-k}\\\\\\P(x=k) = \dbinom{15}{k} 0.2^{k} 0.8^{15-k}\\\\\\$

Then, the probability that exactly five companies that outsource overseas use a consultant is:

$P(x=5) = \dbinom{15}{5} p^{5}(1-p)^{10}=3003*0.0003*0.1074=0.1032\\\\\\$
