A)- The distribution is skewed left.
B)- The histogram has one mode, at 74 to 76 years.
What is histogram?The distribution of numerical data is roughly shown by a histogram. Karl Pearson is credited with coining the phrase. The first stage in creating a histogram is to "bin" (or "bucket") the range of values, or split it into a series of intervals, and then count how many values fall into each interval. The bins are often defined as a series of discrete intervals that don't overlap. Histograms provide a general idea of the density of the underlying distribution of the data, and are frequently used for density estimation: estimating the probability density function of the underlying variable. The bins (intervals) must be adjacent and are frequently (but not always) of equal size.

-6 and -4
Answer:
-5
Step-by-step explanation:
Let's assume the you are moving horizontally along the number line. If you start at -4 and jump to -6, you have made 2 jumps to the left(-4;-5;-6). So halfway between them (the midpoint) is 1 jump (half of 2 jumps).

What did I do wrong ? Question is 7x + 5 = 6x
Answer: Look at the explanation.
Step-by-step explanation: So first you move the 6x to the left side of the equal sign, then u turn it into a negative number. Next, you do 7x-6x=5. Which is 2x=5. And to find x you do 5÷2. Which is 2.5.
Hope this helps!
Answer:
x = -5
Step-by-step explanation:
Let's solve the problem,
→ 7x + 5 = 6x
→ 7x - 6x = -5
→ [ x = -5 ]
Hence, the answer is -5.
three friends ate at restaurant. They ordered nachos for S19 95 and jalapeno poppers. Each friend paid $9.73, not including sales tax or tip, which was 1/3 of the total determine the cost of the jalapeno poppers
The total cost of a Jalapeno is $ 9.24
Three friends ate at a restaurant and ate nachos for $19.95 and jalapeno poppers.
Three of them paid $9.73 each
So the total amount of money paid by three friends = 3×9.73
= 29.19
Now we have to calculate the cost of jalapeno poppers
Therefore we have,
Total amount of money paid = cost of nachos + cost of jalapeno poppers
29.19 = 19.95 + cost of jalapeno poppers
The cost of jalapeno poppers =29.19 - 19.95

the probability that a carton of eggs taken from the cooler at a store will have at least one cracked egg is 2.5%.2.5%. what are the odds that a carton of eggs will have at least one cracked egg?
The odds that a carton of eggs will have at least one cracked egg is 97.5 %
The question has to do with probability
What is probability?Probability is the likelihood for an event to occur. It is given by P(event) = number of required outcomes/total number of possible outcomes.
How to find the odds that a carton of eggs will have at least one cracked egg?Given that the probability that a carton of eggs taken from the cooler at a store will have at least one cracked egg is 2.5%. Let the probability of at least one cracked egg be P(egg ≤ 1) = 2.5% = 0.025
Now, since we require the probability of that a carton of eggs will have at least one cracked egg, that is the number of cracked is greater than 1.
Let the probability of cracked eggs greater than 1 be P(egg ≥ 1).
From the law of probability
P(egg ≤ 1) + P(egg ≥ 1) = 1
So, P(egg ≥ 1) = 1 - P(egg ≤ 1)
P(egg ≥ 1) = 1 - 0.025
P(egg ≥ 1) = 0.975
P(egg ≥ 1) = 0.975 × 100 %
P(egg ≥ 1) = 97.5 %
So, the odds that a carton of eggs will have at least one cracked egg is 97.5 %

Find the total amount given the original price and tax rate. round to the nearest hundredth if necessary. original price: $123.28 tax rate: 7.5% enter the correct answer in the box.
The Total amount to pay including the tax will be $132.52
In the given question, For the Total amount, we know that we have to add the Tax rate to the Principal amount. It is mentioned that the Principal amount P = $123.28 and the Tax rate is 7.5%. Firstly we have to calculate what amount of interest is to be charged upon the Principal amount. To calculate Interest we have the formula :
=> I = (P * R)/100 , where I = Interest, P = Principal Amt, R = Interest Rate
=> I = (123.28 * 7.5)/100 => I = 9.24
We get Interest amount = $9.24
To calculate the Total amount, We have the formula: T = P + I
where, T = Total Amount, P = Principal Amount, and I = Interest Amount
=> T = 123.28 + 9.24 => T = 132.52
Hence, the Total Amount is $132.52

We get the consecutive numbers as 257 and 258 from the equation 2 x + 1 = 515.
We are given that,
The sum of 2 consecutive numbers is 515.
Consecutive numbers:
Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers. For example: 1 and 2 are consecutive numbers, 34 and 35 are also consecutive numbers.
Here let the first number be x
Second number will be:
x + 1
We need to find their sum:
x + x + 1 = 515
2 x + 1 = 515
2 x = 515 - 1
2 x = 514
x = 514 / 2
x = 257
x + 1 = 257 + 1 = 258
