Answer: 50

Explanation:

Given that 5% of the values are absent, the anticipated number of records to be deleted corresponds to the expected value regarding the records with missing values, which has a probability of 0.05.

Thus, the expected number of records to be removed is calculated using

Expected Value = (number of records)(probability of missing value)
= (1000)(0.05)
Expected Value = 50

In which diagram are angles 1 and 2 vertical angles?
PIT_PIT [9121]

Response

The first diagram displays angles 1 and 2 as vertical angles.

Clarification

In all four diagrams, the initial one illustrates the vertically opposite angles.

Angles 1 and 2 are classified as vertically opposite because they face each other.

These angles maintain equal measurement when two lines intersect, resulting in four angles where two pairs of vertically opposite angles are formed.

In contrast, all other figures depict angles 1 and 2 as adjacent angles.

Distance formula:
d= \sqrt{ (x_{2}-x_{1}) ^{2}+( y_{2} - y_{1} )^{2}}\\ d= \sqrt{ (3-(-1)) ^{2}+(1 - 4 )^{2}}\\ d= \sqrt{ (4) ^{2}+(-3)^{2}}\\ d=\sqrt{16+9}\\ d=\sqrt{25}\\ d=5

5 units-4.5 units=0.5 units

Segment LM exceeds segment JK by 0.5 units.

Inessa [9006]

Answer:

You need to purchase 3 shirts to be able to use your coupon.

Step-by-step explanation:

Each shirt originally costs $17.99.

There is a 20% discount on this specific brand of shirts.

$17.99 × 0.2 = $3.60 (discount per shirt)

Subtracting the discount from the original price:

$17.99 - $3.60 = $14.39 (price per shirt after discount)

To qualify for the $10 off coupon which requires a $40 minimum purchase:

$40 ÷ $14.39 ≈ 2.779, rounded up to 3 shirts

Therefore, you must buy 3 shirts.

3 shirts × $14.39 = $43.17, surpassing the $40 minimum needed to apply the $10 discount.

Three workers at a fast food restaurant pack the take-out chicken dinners. John packs 45% of the dinners, Mary packs 25% of the
Inessa [9006]
The likelihood that Mary was the one who packed the dinner stands at 0.15625. To clarify, the probability of an event is defined as the chance that it will occur relative to the total possible outcomes. Let's analyze the problem at hand, which pertains to Conditional Probability. The formula we use generally is as follows: Let: The chance of John packing dinners without a salt packet is denoted as P(J), for Mary, it is P(M), and for Sue, it is P(S). Hence, if there's no salt in the dinner I purchased, the probability that Mary did the packing is calculated as follows.

Inessa [9006]
$29,580. Breaking it down: 29000/4 equals 7250. So, 7250 plus 2% of 7250 calculates as follows: 7250 + (2/100) * 7250 gives us 7250 + 145, totaling $7395 with four payments resulting in $29,580.
