If you have a negative value for m what quadrants will the line be in?

Mathematics

True [87]3 years ago

8 0

Answer:

If the slope of a line is negative, the line WILL intersect quadrants II and IV. X and Y intersects of the line with negative slope have the same sign. Therefore if X and Y intersects are positive, the line intersects quadrant I; if negative, quadrant III.

Jill says that 12.6 reaping is less than 12.63.Explain her error

netineya [11]

12.6 repeating would be 12.666666666666666666..... That's larger then 12.63 because the number in the hundredths place is larger 6 is larger than 3

Determine the modulus of each of the complex numbers in the matching pairs. List these moduli in order from smallest to largest.

slava [35]

Answer:

the modulus of a complex number z = a + bi is:

Izl= √(a²+b²)

The fact that n is complex does not mean that n doesn't has a real part, so we must write our numbers as:

m = 2 + 6i

n = a + bi

Im + nl = 3√10

√(a² + b²+ 2²+ 6²)= 3√10

√(a^2 + b^2 + 40) = 3√10

squaring both side

a²+b²+40 = 3^2*10 = 9*10 =90

a²+b²= 90 - 40

a²+b²=50

So,

|n|=√(a^2 + b^2) = √50

The modulus of n must be equal to the square root of 50.

now

values a and b such

a^2 + b^2 = 50.

for example, a = 5 and b = 5

5²+5²=25+25= 50

Then a possible value for n is:

n = 5+5i

19% of 288 i need help

Helga [31]

Answer:

54.72

Step-by-step explanation:

multiply 19% by 0.01
multiply 0.19 by 288

19·0.01=0.19

0.19·288=54.72

Therefore, 19% of 288 will be 54.72.

A golf association sets performance standards for golf balls. For example, the initial velocity of the ball may not exceed 250

Oksanka [162]

Answer:

In this context 38% represents that if the mean speed of ball is 250 ft/sec, then there is 34% chance of obtaining a similar or more extreme value related to test statistics.

Step-by-step explanation:

We are given that the initial velocity of the ball may not exceed 250 feet per second when measured by an apparatus approved by the association.

Based on the mean speed in the sample, the association comes up with a P-value of 0.38.

Let $\mu$ = mean speed of the ball

So, Null Hypothesis, $H_0$ : $\mu$ = 250 ft/sec

Alternate Hypothesis, $H_A$ : $\mu$ > 250 ft/sec

Now, the P-value given to us is 0.38.

P-value basically tells us the exact percentage where our test statistics lie. Also, it is the probability of obtaining the value that is more extreme, given that null hypothesis is true,

So, in this context 38% represents that if the mean speed of ball is 250 ft/sec, then there is 34% chance of obtaining a similar or more extreme value related to test statistics.
