Answer:

in regards to ratios, think of fractions. If we have a ratio of 3:5, that means that in fraction form we can think of it as

---

If put this into a calculator (3 divided by 5), you will get a decimal of 0.6 as the answer. This means that any two numbers that divide and come to the same answer are equivalent to 3/5.

Now, from what it appears you are asking, they want you to find two other numbers that come to the same ratio / answer of 0.6, and that these numbers should be double. To do this, simply multiply the numerator and denominator by 2, which is double.

3 x 2 = 6

5 x 2 = 10

So our fraction now is

---

If you put that into a calculator (6 divided by 10), it will come to the same answer of 0.6. Therefore, this fraction / ratio is equivalent to the original.

If your answer is expected to be in ratio format, then it should be 6:10

First

angle in front of c is 30°, so hypotenuse is equal to 2c

it's right triangle, so let's use Pythagorean theorem\

$(2c)^2=c^2+4^2\\4c^2=c^2+16\\3c^2=16\\\\c^2=\dfrac{16}{3} \\\\c=\dfrac{4}{\sqrt{3} } =\dfrac{4\sqrt{3} }{3 }$

Second

b - the base of the triangle, angles at the base are equal ⇒ cathets are equal

it's right triangle, so let's use Pythagorean theorem

$b^2=7^2+7^2\\b^2=49+49\\b=\sqrt{2\times49} =7\sqrt{2}$

The measurement of the height of 600 students of a college is normally distributed with a mean of

ioda

Answer:

Step-by-step explanation:

We let the random variable X denote the height of students of the college. Therefore, X is normally distributed with a mean of 175 cm and a standard deviation of 5 centimeters.

We are required to determine the percent of students who are between 170 centimeters and 180 centimeters in height.

This can be expressed as;

P(170<X<180)

This can be evaluated in Stat-Crunch using the following steps;

In stat crunch, click Stat then Calculators and select Normal

In the pop-up window that appears click Between

Input the value of the mean as 175 and that of the standard deviation as 5

Then input the values 170 and 180

click compute

Stat-Crunch returns a probability of approximately 68%

Find the equation, in point-slope form, of the line that passes -3 and passes through the point (1,2). plz show your work.

Maslowich

Substitute the given values for the parameters in the point-slope form of the equation of a line. That form is
y - k = m(x - h)
for point (h, k) and slope m.

You have (h, k) = (1, 2) and m=-3, so your equation is
y - 2 = -3(x - 1)
