gavmur [86]

Answer:

The value of a is 7.4833. The value of $A=29.9262^0$ and $B=60.0735^0$ .

Step-by-step explanation:

Consider the provided information.

The required figure is shown below:

We need to find the value of a.

Calculate the value of a by using Pythagorean theorem.

$a^2+b^2=c^2$

$a^2+(13)^2=(15)^2$

$a^2=225-169$

$a^2=56$

$a=7.4833$

Hence, the value of a is 7.4833.

Now find the value of angle A as shown:

$\sin A=\frac{a}{c}$

$\sin A=\frac{7.4833}{15}$

$A=sin^{-1}(0.4989)$

$A=29.9262^0$

Find the value of angle B as shown:

$\sin B=\frac{b}{c}$

$\sin B=\frac{13}{15}$

$B=sin^{-1}(0.8667)$

$B=60.0735^0$

Hence, the value of $A=29.9262^0$ and $B=60.0735^0$ .

Explain in your own words how you would graph the equation y = -4x + 25

madam [21]

Answer:

See below

Step-by-step explanation:

First, I would choose three different points with some distance between. Let's do x = -5, x = 0, and x = 5. Next, I would plug those numbers into the equation, like so:

$y = -4(-5) + 25 = 20 + 25 = 45$

$y = -4(0) = 25 = 25$

$y = -4(5) + 25 = -20 = 25 = 5$

Next, I would plot the points [(-5, 45), (0, 25), (5, 5)] on an x-y graph. Finally, I would take a ruler, line it up with the three points, and draw a line through those three points, extending from one side of the graph to the other to show the equation is continuous.

The mean weight of the domesticated house cat is 9.2 pounds with a standard deviation of 3.4 pounds. If a cat has a z-score of -

ra1l [238]

Answer:

4.78 pounds

Step-by-step explanation:

We solve the above question using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean = 9.2 pound

σ is the population standard deviation = 3.4 pounds

z = 1.3

We are to find x

Hence,

-1.3 = x - 9.2/3.4

Cross Multiply

-1.3 × 3.4 = x - 9.2

-4.42 = x - 9.2

x = -4.42 + 9.2

x = 4.78 pounds.

Therefore the weight of the cat is 4.78 pounds
