Answer:

12.66666 infinity or 38/3

Step-by-step explanation:

Parentheses first so 5-2 is 3... then multiply so then 12... 12+32-6 is 38. 38 over 3 is 12.6666 infinity or 38/3, cannot be simplified...

In applications, we consider any event that has below 5% chance. Pick a card from a standard deck of 52 cards. A=The card is an

9966 [12]

Answer:

Step-by-step explanation:

P(A) = 4/52 = 0.07692 which is bigger than 5%

5% = 0.05

0.07 is above 5% which is surprising.

The P(Spade A) = 1/52 = 0.01923 which is under 2% which meets your criteria.

Find the equation of the line that passes through (3,1) and is parallel to y=2x+3

ICE Princess25 [194]

Answer:

y -1 = 2(x -3)

Step-by-step explanation:

The given equation is in slope-intercept form:

y = mx +b . . . . line with slope m and y-intercept b

y = 2x +3 . . . . . line with slope 2 and y-intercept 3

A parallel line will have the same slope. Since you are given a point, it is convenient to use the point-slope form for the equation you want:

y -k = m(x -h) . . . . . line with slope m through point (h, k)

y -1 = 2(x -3) . . . . . . line with slope 2 through point (3, 1)

<em>Additional comment</em>

If you want the slope-intercept form you can solve for y:

y = 2(x -3) +1 = 2x -6 +1

y = 2x -5 . . . . . slope-intercept form of the parallel line

Josie took a long multiple-choice, end-of-year vocabulary test. The ratio of the number of problems Josie got incorrect to the n

FrozenT [24]

Answer:

A. Josie got 36 correct answers.

B. Josie got 90 correct answers.

C. 8:36 and 20:90

D.6:27, 12:54, 30:135, among others.

e. Multiply both numbers on the ratio by the same constant integer, thereby ensuring that the resulting numbers form a ratio equivalent to the original.

Step-by-step explanation:

Very well, so the statement is that Josie got 2 problems incorrect for every 9 that she got correct. First the ask how many questions she got correct given that she missed 8 question. First, we divide the 8 question she missed by 2. Now have 4 pairs of questions that Josie missed and for every pair that she failed; Josie got 9 questions correctly. Therefore, we multiply 4 pairs of incorrect questions times 9 correct questions. So, if Josie had 8 incorrect questions, she also had 36 correct answers on her test.

In the case that Josie missed 20 questions, we divide them by two again in order to obtain the number of pairs that Josie missed. Now have 10 pairs of questions that Josie missed and for every pair that she failed; Josie got 9 questions correctly. Therefore, we multiply 10 pairs of incorrect questions times 9 correct questions. So, if Josie had 8 incorrect questions, she also had 90 correct answers on her test.

With the information we collected, we can affirm that the ratios 8:36 and 20:90 are equivalents to the original 2:9 that was stated. Other examples of equivalents ratios could be 6:27, 12/54, 30:135, among many others.

To find the equivalent ratios what we need to do is find common multiples of the numbers that conform the ratio. To do so, we can multiply both numbers by the same constant integer, thereby ensuring that the resulting numbers form a ratio equivalent to the original.

Have a nice day! :D
