Answer:

6 5/12 and 5 1/30

Step-by-step explanation:

Just simplify both sides of the equation.

1 3/4 + 1/6 + x = 7 1/2 ---> 1 11/12 + x =7 1/2

then subtract the 1 11/12 from both sides

x = 6 5/12

Leonardo decided to start training to run in a marathon to keep in shape. After 5 training sessions, he had run a total of 25 mi

lisov135 [29]

Total distance ran by Leonardo in 5 training sessions = 25 miles
Then
Total distance ran by Leonardo in 1 training session = (25/5) miles
= 5 miles
Total distance ran by Leonardo today was half the distance he actually covers in every training session.
So
Total distance ran by Leonardo today = (5/2) miles
= 2.5 miles
So Leonardo ran for a distance of 2.5 miles today. <span>It is actually very important to read the question carefully and then the answering the question becomes easy.

Suppose a shipment of 120 electronic components contains 3 defective components. to determine whether the shipment should be ac

Likurg_2 [28]

For this problem, the most accurate is to use combinations

Because the order in which it was selected in the components does not matter to us, we use combinations

Then the combinations are $nC_r = \frac{ n! }{r! (n-r)!}$

n represents the amount of things you can choose and choose r from them

You need the probability that the 3 selected components at least one are defective.

That is the same as:

(1 - probability that no component of the selection is defective).

The probability that none of the 3 selected components are defective is:

$P = \frac{_{117}C_3}{_{120}C_3}$

Where $_{117}C_3$ is the number of ways to select 3 non-defective components from 117 non-defective components and $_{120}C_3$ is the number of ways to select 3 components from 120.

$_{117}C_3 = 260130$

$_{120}C_3 = 280840$

So:

$P = \frac{260130}{280840} = 0.927$

Finally, the probability that at least one of the selected components is defective is:

$P = 1-0.927 = 0.0737$

P = 7.4%

Identify the scale factor when we scale up from Figure S to T. Just write the number.

Sergeu [11.5K]

Answer:

Scale factor = 4

Step-by-step explanation:

Scale factor = $\frac{\text{Dimension of the image}}{\text{Dimension of preimage or original}}$

Since, S is being dilated with a scale factor to form T,

So, the figure S is the preimage and figure T will be the image,

Length of one side of image T = 8

Length of one side of preimage = 2

Therefore, Scale factor = $\frac{8}{2}$

= 4

Scale factor by which figure S has been dilated to form figure T is 4.

Which is the closest to the curve of best fit for the data shown?

docker41 [41]

Answer:

data shows a positive or negative correlation, we can model the trend in the data using a line of best fit. Example 1 ... A curve of best fit is used to find an equation that best fits a quadratic function.
