since BAD = 125

180-125 = 55 so ADC = 55

ADC = GHE so GHE = 55 degrees

Line that is parallel to y= -3/2x-1

VLD [36.1K]

Answer:

See below.

Step-by-step explanation:

There is an infinite number of lines parallel to y = -3/2x - 1.

They have the same slope, -3/2, and a different y-intercept.

Examples:

y = -3/2x + 1

y = -3/2x

y = -3/2x - 5

A fish was swimming 3 in a half feet below the water surface at 7:00 a.M. Four hours later, the fish as at a depth that is 5 one

Mekhanik [1.2K]

Answer:

8 3/4 below sea level

Step-by-step explanation:

Given that:

Depth of fish at 7:00 A. M = 3 1/2 feets below sea level

Depth at 11:00a.m (4 hours later) = 5 1/4 feets below it's position at 7:00 a. M

Rational number to represent position of fish with respect to the water surface at 11:00 a. M

Position at 11:00 a. M :

Addition of the two depth distances given :

(3 1/2 + 5 1/4)

7/2 + 21/4 = (14 + 21) / 4 = 35 / 4

35/4 = 8 3/4 feets below sea level

The principal at Riverside High School would like to estimate the mean length of time each day that it takes all the buses to ar

Lilit [14]

Answer:

C) 11

Step-by-step explanation:

1) Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

$\bar X$ represent the sample mean for the sample

$\mu$ population mean (variable of interest)

s represent the sample standard deviation

n represent the sample size

Since the Confidence is 0.90 or 90%, the value of $\alpha=0.1$ and $\alpha/2 =0.05$ , and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-NORM.INV(0.05,0,1)".And we see that $z_{\alpha/2}=1.64$

The margin of error is given by this formula:

$ME=z_{\alpha/2}\frac{s}{\sqrt{n}}$

And on this case we have that ME =7 and we are interested in order to find the value of n, if we solve n from the last equation we got:

$n=(\frac{z_{\alpha/2} s}{ME})^2$

And replacing the values that we got we have:

$n=(\frac{1.64(14)}{7})^2 =10.758 \approx 11$

which of the following illustrates the commutative property for multiplication,A: 1•m=m or 3•m•6=3•6•m

algol [13]

The first one is reflexive, which states that anything equals itself.

The second is the commutative property for multiplication, as it states that it doesn't matter what order you multiply the numbers in, the product remains the same :)
