for every five baseball cards that Mickey has Mike has 3 baseball cards if Mike has 72 baseball cards how many cards does Mickey have?
Mickey has 3 cards.
Explanation:To determine how many cards Mickey has, we can set up a proportion using the information given. We know that for every five cards Mickey has, Mike has 3 cards. So the proportion would be: (Mickey's cards) / 5 = 3 / (Mike's cards).
Given that Mike has 72 cards, we can plug that into the proportion: (Mickey's cards) / 5 = 3 / 72.
To solve for Mickey's cards, we can cross multiply: (Mickey's cards) = (3 / 72) * 5.
After simplifying, we find that Mickey has 3.125 cards. However, since we can't have a fraction of a card, we know that Mickey has 3 cards.

I need to skip count by ten from 350 to 240
Skip counting by ten from 350 to 240 involves starting at 350 and counting backwards by subtracting ten each time until you reach 240. The sequence would look as follows: 350, 340, 330, 320, 310, 300, 290, 280, 270, 260, 250, 240.
Explanation:In Mathematics, when asked to 'skip count' it means that you are counting up or down by a specified number, in this case, by ten. However, the student's question asks to skip count by ten from 350 to 240, which would require counting backwards or decreasing the count by ten each time.
To skip count by ten from 350 to 240, you would start at 350 and then subtract 10 each time, like this: 350, 340, 330, 320, 310, 300, 290, 280, 270, 260, 250, 240. Note: 240 is included in the sequence as it is the final number we're skip counting down to.

Find JL if JK = 17 - x, KL = 2x - 7, and K is the midpoint of JL
Final answer:
By setting up an equation where JK equals KL since K is the midpoint, solving for x, and substituting back to find the length of JL, we find that JL is 18 units long.
Explanation:
To find the length of JL when given that JK = 17 - x and KL = 2x - 7, and knowing that K is the midpoint of JL, we can form an equation recognizing that JL is the sum of JK and KL. Because K is the midpoint, we know that JK and KL are actually equal in length, so we can set them equal to each other and solve for x:
17 - x = 2x - 7
Combining like terms by adding x to both sides and adding 7 to both sides gives us:
24 = 3x
Dividing both sides by 3:
x = 8
Since JK and KL are equal and K is the midpoint, JL will be twice the length of either segment. Substituting x into either expression, JK or KL:
JL = 2 * JK = 2 * (17 - x) = 2 * (17 - 8) = 2 * 9 = 18
or
JL = 2 * KL = 2 * (2x - 7) = 2 * (2*8 - 7) = 2 * (16 - 7) = 2 * 9 = 18
Therefore, JL = 18.

Use the distributive property of multiplication to find the missing number.use the distributive property of multiplication to find the missing number.
The distributive property of multiplication involves multiplying a number with each term inside a bracket, then adding or subtracting the results. To find a missing number, set up an equation based on the distributed multiplication and solve for the unknown.
Explanation:The distributive property of multiplication can be simply defined as a(b + c) = ab + ac. In this equation, 'a' is distributed over 'b' and 'c', which means we multiply 'a' individually with 'b' and 'c', and then add the results.
Let's consider an example: 2(3 + 4) = ? Here, applying the distributive property, we multiply 2 with 3 and 2 with 4 separately. Hence, 2*3 + 2*4 = 6 + 8 = 14. So, the result is 14.
To solve distribution problems with a missing number, you would set up the equation and solve for the unknown. For example, if we have 3(x+5) = 21, we can first distribute the 3 to get 3x + 15 = 21. Then, you'd subtract 15 from both sides to isolate the 'x'. So, 3x = 21 - 15, which simplifies to 3x = 6. Finally, dividing both sides by 3 gives x = 2. So, the missing number is 2.

To find the area under the normal distribution curve for a range of z-values, you refer to a z-table and possibly subtract two areas to find the area between two z-values. The areas above were calculated as examples.
Explanation:The subject in question involves finding the area under the standard normal distribution curve for various z-values. This is a concept in statistics that evaluates the probability which a particular range of values under the normal distribution curve might occur.
For z between 0 and 1.95, we refer to the z-table and find the area under the curve as 0.975.For z between 0 and 0.37, using the z-table, the area under the curve is 0.644.For z between 1.32 and 1.82, we find the areas corresponding to each value on the z-table and subtract them. This is 0.9664 - 0.9066 = 0.0598.For z between 1.05 and 2.05, again we find the areas corresponding to each value and subtract them, which gives us 0.975 - 0.8543 = 0.1207.For z between 0.03 and 0.53, we find the corresponding areas and subtract, resulting in 0.7054 - 0.5120 = 0.1934.Learn more about standard normal distribution here:https://brainly.com/question/29509087

Complete the point-slope equation of the line through (1,3) and (5,1)
The point-slope equation of the line through (1,3) and (5,1) is y - 3 = -0.5(x - 1), where the slope m= -0.5 was calculated using the formula m = (y2 - y1) / (x2 - x1).
Explanation:To complete the point-slope equation of the line through points (1,3) and (5,1), we first need to find the slope of the line, which can be calculated using the formula: m = (y2 - y1) / (x2 - x1), here (x1,y1) and (x2,y2) are the coordinates of two points on the line.
Substituting in the given coordinate values gives us m = (1 - 3) / (5 - 1), which simplifies to m = -0.5, indicating a downward slope.
The point-slope form of the equation of a line is y - y1 = m(x - x1). So, substituting one of the given points (1, 3) and the calculated slope into the point-slope form gives us y - 3 = -0.5(x - 1).
Therefore, the point-slope equation of the line through (1,3) and (5,1) is y - 3 = -0.5(x - 1).

Answer:
CPCTC; JP≅MI; SAS
Step-by-step explanation:
For the first question, we use the congruence statement. When we are using the congruence statement to match corresponding pieces, the justification is that Congruent Parts of Congruent Triangles are Congruent, or CPCTC.
For the second question, we again use CPCTC and the congruence statement. P matches T and B matches I, so PB = TI and B = I. J matches M also, so BJP = IMT. However, P does not match I, so JP does not equal MI.
For the third question, we have two sides (AM matching ZD and BD matching itself) and an included angle (AMD and ZDM). This is Side-Angle-Side, or SAS.

A 2005 study by the fisheries research services in aberdeen, scotland, suggests that the average length of the species clupea harengus (atlantic herring) as a function of age t (in years) can be modeled by l(t) = 32(1 − e−0.37t) cm for 0 ≤ t ≤ 13. how fast is the length changing at age t = 7 years?
The rate of change of length of the Clupea harengus (Atlantic herring) at t = 7 years is approximately 2.8 cm per year.
Explanation:To determine how fast the length of Clupea harengus (Atlantic herring) is changing at age t = 7 years, you need to calculate the derivative of the given function, l(t) = 32(1 − e−0.37t), with respect to time. The derivative measures the rate of change of a function, which in this case corresponds to the speed of growth of the herring.
The derivative of l(t) with respect to t is given by: l'(t) = 32 * 0.37e^(-0.37t).
Substitute t = 7 into this derivative function to get: l'(7) = 32 * 0.37e^(-0.37*7) ≈ 2.8 cm/year.
So, the length of the Atlantic herring is increasing at approximately 2.8 cm per year when the herring is 7 years old.

To find the rate at which the length of the Atlantic herring is changing at age t = 7 years, we need to take the derivative of the length function and evaluate it at t = 7.
Explanation:To find the rate at which the length of the Atlantic herring is changing at age t = 7 years, we need to find the derivative of the length function with respect to time. The function l(t) = 32(1 − e−0.37t) represents the average length of the herring at age t. Taking the derivative of this function gives us:
l'(t) = 32 * (-0.37) * e−0.37t
Now, we can substitute t = 7 into the derivative to find the rate of change at that age:
l'(7) = 32 * (-0.37) * e−0.37(7)
This expression can be simplified further to find the exact value of the rate of change.
