Step-by-step explanation: i took the test

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

Sin 30 = 5/x

Sin 30 = 1/2

x = 10

The length of the side x is 10.

There are three commonly used trigonometric identities.

We have,

The length of side x can be calculated using the trigonometric identities.

We know that,

Sin x = Perpendicular / Hypotenuse

Sin 30 = 5 / x

1/2 = 5/x

Multiply 2 on both sides.

1= 10/x

x = 10

Thus,

The length of the side x is 10.

Answer: d) A one-sample z-interval for a population proportion

Step-by-step explanation:

For the scenario described above, since only a single sample pool is required from a single population, then ; The one sample Z interval for a population proportion is required ;

The interval may be calculated using the relation :

Z = (p - p0) / √[(p0(1 - p0)) / n]

p = observed proportion ;

p0 = mean or hypothesized value

n = sample size

Answer:

26cm²

Step-by-step explanation:

Perimeter

2x - 4 + 5x - 13 + x + 9 = 40

8x - 8 = 40

8x = 40 - 8

8x = 32

x = 4

Sides of the triangle

Height = 2x - 4 = 2 x 4 - 4 = 4cm

Hypotenuse = 5x - 13 = 5 x 4 - 13 = 7cm

Base = x + 9 = 4 + 9 = 13cm

Area of triangle

Answer:

0.07 ; 0.65 ; 0.00064339296875 ; 3.02 * 10^-12

Step-by-step explanation:

Given :

Number of monkeys, n1 = 10

Probability of fall, off ; p(m) = 35% = 0.35

Number of kangaroos, n2 = 5

Probability of fall, off : p(k) = 20% = 0.2

1.) A monkey and kangaroo falls off;

p(m) * p(k) = 0.35 * 0.2 = 0.07

2.) probability that monkey will not fall off;

1 - p(m) = 1 - 0.35 = 0.65

3.) probability that a monkey falls off every one of seven nights :

P(m) = 0.35 ; for 7 nights ;

0.35 *0.35 * 0.35 * 0.35 * 0.35 * 0.35 * 0.35 = 0.35^7 = 0.00064339296875

4.)

P(x ≥ 1) = p(1) + p(2) +... + p(10)

Using binomial probability calculator :

n = 7*10 = 70 ; p = 0.35

P(x ≥ 1) = 70C1 * 0.35^1 * 0.65^69 = 3.02 * 10^-12

Answer:

[tex]23.1\%[/tex]

Step-by-step explanation:

Stefanie's mixture of 18 grams has a 20% sugar content. Therefore, there are  grams of sugar in her syrup.

John's mixture of 30 grams has a 25% sugar content. Therefore, there are  grams of sugar in her syrup.

Therefore, if they mix their syrups together, there will be 11.1 grams of sugar and 48 total grams of content.

The concentration of sugar in the new mixture is [tex]\frac{11.1}{48}=\fbox{$23.1\%$}[/tex](rounded to one decimal place).

The concentration in the new mixture is 23.1%.

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.

Stefanie's 18-gram combination has 20% sugar. As a result, her syrup contains grams of sugar.

John's 30-gram combination contains 25% sugar. As a result, her syrup contains grams of sugar.

As a result, if they combine their syrups, there will be 11.1 grams of sugar and 48 total grams of the substance.

The new combination has a sugar percentage of 11.1/48 = 23.1%. (rounded to one decimal place).

Answer:3 + ? = 7, 3 + n = 7, 3 + x = 1

Step-by-step explanation:

and so on, where the symbols ?, n, and x represent the number we want to find. We call such shorthand versions of stated problems equations, or symbolic sentences. Equations such as x + 3 = 7 are first-degree equations, since the variable has an exponent of 1. The terms to the left of an equals sign make up the left-hand member of the equation; those to the right make up the right-hand member. Thus, in the equation x + 3 = 7, the left-hand member is x + 3 and the right-hand member is 7.

Answer:

Inequality Form:  x < −1

Interval Notation:  (−∞, −1)

Step-by-step explanation:

3 (x + 3) −2 < 4

Simplify 3 (x + 3) − 2.

Apply the distributive property.

    3x + 3 ⋅ 3 − 2 < 4

Multiply 3 by 3.

    3x + 9 − 2 < 4

Subtract 2 from 9.

    3x + 7 < 4

Move all terms not containing x to the right side of the inequality.

Subtract 7 from both sides of the inequality.

    3x  < 4 − 7

Subtract 7 from 4.

    3x  < −3

Divide each term by 3 and simplify.

    x < −1

The result can be shown in multiple forms.

Answer:

B)   All real values of 'x' where -2 < x< 4

Step-by-step explanation:

Explanation:-

Given function f(x) = (x +2 ) ( x-4)

                  (x+2)(x-4) =0

          ⇒  x +2 =0 and x-4=0

          ⇒  x =-2   and x=4

From graph

       Given parabola lies between the x=-2 and x =4

∴ All real values of 'x' lies between x=-2 and x =4

 All real values of 'x' lies -2 < x< 4

Answer: r= A-P/ Pt

Step-by-step explanation: ur welcome

The equation [tex]r = \frac{A-P}{pt}[/tex] is correctly solved for r.

Here,

The formula shown can be used to find A the amount of money Raul has in his saving account.

Raul wants to find r the rate of interest his money earns.

We have to find the equation is correctly solved for r.

What is Rate of interest?

The interest rate is the amount a lender charges a borrower and is a percentage of the principal—the amount loaned.

Now,

The formula which shown to find A is;

A = P + Prt

Hence, equation is correctly solved for r is;

[tex]A = P + Prt\\\\A-P = Prt\\\\r = \frac{A-P}{Pt}[/tex]

So, The equation [tex]r = \frac{A-P}{pt}[/tex] is correctly solved for r.
