Francine and Cheryl received equal scores on a test made up of multiple choice questions and an essay. Francine got 34 multiple

kipiarov [429]

$34x + 14 = 30x + 22$
X is the amount the multiple choice question is worth. Both girls had the same test score so both are equal. Isolate X and that will be the value.

$34x -( 30x) + 14 = 22$
$4x = 22 - (14)$
$4x = 8$
$4x \div 4 = 8 \div 4$
x = 2

Plug 2 back in for x in the original equation to check and both girls recieved a 82%

A student randomly guesses on 10 true/false questions. use the binomial model to determine the probability that the student gets

lana [24]

Answer:

$P(5)=\frac{63}{256}$

Step-by-step explanation:

we are given

A student randomly guesses on 10 true/false questions

so,

$n=10$

there only true and false

so, probability getting true question is

$p=\frac{1}{2}$

so, probability getting false question is

$q=\frac{1}{2}$

the student gets 5 out of 10 questions right

so,

r=5

we can use binomial probability formula

$P(r)=\frac{n!}{r!(n-r)!} p^rq^{n-r}$

now, we can plug values

$P(5)=\frac{10!}{5!(10-5)!} (\frac{1}{2})^5(\frac{1}{2})^{10-5}$

we can simplify it

and we get

$P(5)=\frac{63}{256}$

Nikki drew a rectangle with a perimeter of 18 units on a coordinate grid. Two of the vertices were (4, –3) and (–1, –3). What co

Talja [164]

Answer:

There are two possible solutions for the other two vertices of the rectangle:

(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)

Step-by-step explanation:

Geometrically speaking, the perimeter of a rectangle ( $p$ ) is:

$p = 2\cdot b + 2\cdot h$ (1)

Where:

$b$ - Base of the rectangle.

$h$ - Height of the rectangle.

Let suppose that the base of the rectangle is the line segment between (4, -3) and (-1, -3). The length of the base is calculated by Pythagorean Theorem:

$b = \sqrt{[(-1)-4]^{2}+[(-3)-(-3)]^{2}}$

$b = 5$

If we know that $p = 18$ and $b = 5$ , then the height of the rectangle is:

$2\cdot h = p-2\cdot b$

$h = \frac{p-2\cdot b}{2}$

$h = \frac{p}{2}-b$

$h = 4$

There are two possible solutions for the other two vertices of the rectangle:

(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)

Write the function tan(<img src="https://tex.z-dn.net/?f=%5Cfrac%7B3%5Cpi%20%7D%7B4%7D%20-x" id="TexFormula1" title="\frac{3\pi

Alenkasestr [34]

Step-by-step explanation:

$\tan( \frac{3\pi}{4}- x) = \frac{ \tan( \frac{3\pi}{4} ) - \tan(x) }{1 + \tan( \frac{3\pi}{4} ) \tan(x)}$

Since tan(3pi/4) = -1

$\tan( \frac{3\pi}{4}- x) = \frac{ - 1 - \tan(x) }{1 - \tan(x)}$

$= \frac{ \tan(x) + 1}{ \tan(x) - 1}$
