Answer:

1024 outcomes

Step-by-step explanation:

Within a particular single question, we can select only 1 correct answer from 2 options. The number of ways of doing this is 2C1 and this is 2

This means for each question, there are only 2 possible outcomes. Now for 10 questions, the total number of possible outcomes would be the outcome of each of the questions multiplied by one another.

That would be (2)^10 which is 1024 outcomes

PLZZ HELPP WILL GIVE BRAINLIEST Graph the line y=25x+3. Use the line tool and select two points on the line. THIS IS A K12 TEST
Sophie [7]

Step-by-step explanation:

you can use any value either in place of x or y to find the corresponding coordinate but if you want to find the x and y intercept you can desigate x as zero and find the y intercept and vice versa.

so to find x and y intercept

y=25x+3. to find x intercept designate y as zero

0=25x+3

-3=25x

x= -3/25. p( -3/25,0)

y=25x+3 to find y intercept designate x as zero

y=25(0)+3

y=3. p(0,3)

the above y and x intercept indicates the points that the line of equation pass through when drawn graphically.

If < A and < B form a linear pair, and < A = x - 13 degrees, and < B = x + 7 degrees, then find x. Select one: a. 12
Andreas93 [3]

The correct value of "x" will be "93".

According to the question,

  • A linear pair of sum to 180°,

then

→ x-13+x+7=180

→             2x -6=180

By adding "6" both sides of the equation, we get

→       2x-6+6=180-6

→                   2x=186

→                     x = \frac{186}{2}

→                     x = 93

Thus "option d" is the right answer.
