Answer:

The probability of selecting a white marble is 0.368

Step-by-step explanation:

Given;

number of red marbles, R = 4

number of white marbles, W = 7

number of blue marbles, B = 8

Total number of marbles in the box = 4 + 7 + 8 = 19

The probability of selecting a white marble is given by;

P(W) = 7 / 19

       = 0.368

Therefore, the probability of selecting a white marble is 0.368

Answer:

4x-7=5

Step-by-step explanation: If you take 4(3) you get 12 -7 =5

Answer:

in an arithmetic sequence, the nth term is the first term +(n-1)times the difference

the difference between the 3rd and 4th term is 18-13=5, so d=5

now we need to find out the first term: 13=a1+(3-1)d => a1=3

the 50th term is a1+(50-1)d=3+49*5=248

Answer:

A

Step-by-step explanation:

Remember that tangent is the ratio of sine over cosine.

[tex]\tan(\theta)=\frac{\sin(\theta)}{\cos(\theta)}[/tex]

In the unit circle:

Our x-coordinate is -√2/2 and our y-coordinate is √2/2.

So, substitute -√2/2 for cosine and √2/2 for sine. This yields:

[tex]\tan(\theta)=\frac{\sqrt2/2}{-\sqrt2/2}[/tex]

Since the numerator and the denominator are the same save for a negative, we can cancel them:

[tex]\tan(\theta)=-1[/tex]

So, our answer is A.

Step-by-step explanation:

The third one, 2 to the power of 5 over 6

√2 * 3√2

convert from radical form to exponent form to solve for the same root

( x^m/n = n√x^m )

2^(1/2) * 2^(1/3)

2^{3/6} * 2^{2/6} - find common denominator (6)

6√(2^3) * 6√(2^2) - convert back to radical form

6√(2^3 * 2^2)- combine

6√(2^5)

then convert to exponential form again

~ 2^5/6 ~

Answer:

3rd answer.

Step-by-step explanation:

Answer:

Circle the 6.

Step-by-step explanation:

In the first line, it states: 40 - 2 × 3² + 10.

Remember to follow PEMDAS. PEMDAS is the order of operation, and equals:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

In this case, instead of applying the power (3² = 3 * 3 = 9), the person simply multiplied (3² ≠ 3 * 2 = 6).

Instead, the order should look like:

40 -2 * 3² + 10

40 -2 * (3 * 3) + 10

40 -2 * (9) + 10

40 + (-2 * 9) + 10

40 + (-18) + 10

50 - 18

Answer:

The Bulldogs gained 11 1/2 yards

Step-by-step explanation:

its sad that they could lose so much ground on a sack. their qb must suck

15 1/2 ---> 15.5

3 1/4 ---> 3.25

-7 1/4 ---> -7.25

15.5+3.25= 18.75

18.75 -7.25= 11.5 ---> 11 1/2 yards

Answer:

[tex]\displaystyle \frac{\frac{3}{4}}{\frac{9}{10}}=\frac{5}{6}[/tex]

Step-by-step explanation:

Fraction Division

The division of two fractions a/b and c/d is usually done by multiplying the first fraction by the reciprocal of the second fraction:

[tex]\displaystyle \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a}{b}\cdot\frac{d}{c}[/tex]

We are required to divide:

[tex]\displaystyle \frac{\frac{3}{4}}{\frac{9}{10}}[/tex]

Applying the above rule:

[tex]\displaystyle \frac{\frac{3}{4}}{\frac{9}{10}}=\frac{3}{4}\cdot\frac{10}{9}=\frac{30}{36}[/tex]

Simplifing by 6:

[tex]\boxed{\displaystyle \frac{\frac{3}{4}}{\frac{9}{10}}=\frac{5}{6}}[/tex]

Answer:

Rigid motions are transformations that maintain congruency. This means that both the pre-image and image will be congruent. This is true because rigid motions do not change the measurements of the sides or angles. Other types of transformations, also called non-rigid motions, like dilations do not maintain congruency.
