The table shows the results of spinning a spinner several times. (Don’t mind my answer)
Answers
The experimental probability of spinning a B or a C is [tex]\( \frac{1}{4} \)[/tex].
To find the experimental probability of spinning a B or a C, we need to sum up the frequencies of outcomes B and C and then divide that by the total number of spins.
Given frequencies:
Outcome A: 3
Outcome B: 2
Outcome C: 1
Outcome D: 4
Outcome E: 2
Total frequency of B and C: 2 (from outcome B) + 1 (from outcome C) = 3
Total number of spins: Sum of all frequencies = 3 + 2 + 1 + 4 + 2 = 12
Experimental probability of spinning a B or a C: [tex]\(\frac{\text{Total frequency of B and C}}{\text{Total number of spins}} = \frac{3}{12} = \frac{1}{4}\)[/tex]
So, the experimental probability of spinning a B or a C is [tex]\(\frac{1}{4}\)[/tex].

an open rectangular cardboard box with a square base is to have a volume of 256cm^3. Find the dimensions of the box if the area of cardboard used is as small as possible
Answers
x------> the length side of the square base of the box
y-------> the height of the box
we know that
volume of the box=b²*h
b=x
h=y
volume=256 cm³
so
256=x²*y------>y=256/x²--------> equation 1
The amount of material used is directly proportional to the surface area, so we will minimize the amount of material by minimizing the surface area.
surface area of the cardboard=area of the base+perimeter of base*height
area of the base=x²
perimeter of the base=4*x
height=y
surface area=x²+4x*y-----> equation 2
substitute equation 1 in equation 2
SA=x²+4x*[256/x²]-----> SA=x²+1024/x
step 1
find the first derivative of SA and equate to zero
2x+1024*(-1)/x²=0------> 2x=1024/x²----> x³=512--------> x=8 cm
y=256/x²------> y=256/8²-----> y=4 cm
the answer is
the length side of the square base of the box is 8 cm
the height of the box is 4 cm
To find the dimensions of the box with the smallest area of cardboard used, we can minimize the surface area of the box using calculus. The volume of the box is given as 256 cm³.
Explanation:To find the dimensions of the box with the smallest area of cardboard used, we need to minimize the surface area of the box. Let's assume that the length, width, and height of the box are L, W, and H, respectively.
The volume of the box is given by V = L * W * H = 256 cm³. Since the box has a square base, we have L = W.
The surface area of the box is given by SA = 2LW + 2LH + 2WH = 2(LW + LH + WH). Substituting L = W into the equation, we have SA = 6L² + 2LH.
To minimize the surface area, we can take the derivative of SA with respect to L and set it equal to zero. Solving this equation will give us the value of L that minimizes the surface area. Once we have the value of L, we can find the corresponding values of W and H using the equation V = L * W * H = 256 cm³.
Using this method, we can determine the dimensions of the box that will result in the smallest amount of cardboard used.

Last month, Luke spent $1,300 on his mortgage (home loan payment), $320 for food, $280 on entertainment, $275 for his car payment, $60 on car insurance, and $75 on clothing. What was the difference for the month between his fixed expenses and variable expenses? A) $1035 B) $1240 C) $960 D) $900
Answers
The fixed expenses are: mortgage, car and insurance
1300 + 275 + 60 = 1635
The variable expenses are: food, entertainment, clothing
320 + 280 + 75 = 675
Subtracting those gives a value of 960.

In this Punnett square, what is the ratio of homozygous to heterozygous offspring? In the Punnett square, what percentage of the offspring are homozygous recessive?
Answers
Start by filling in the rest of the box!
1) Since you know the bottom right square is tt, that means both alleles must be t. You already have the allele of the parent on the left filled in, so fill in the top one with t (shown in green).
2) Since you know the top left square in the 2 by 2 box is Tt, one allele from the parent is T and the other allele is t. You're already given T by the top parent, so fill in the box for the left parent with t (shown in purple).
3) Finally fill in the top right box in the 2 by 2. The top parent donates a t allele (green) and the left parent also donates a t allele (purple). The genotype is tt.
Now back to the questions:
1) Homozygous offspring means that for it's genotype, both alleles are the same: either TT or tt. Heterozygous means that the alleles are different: Tt.
Looking at the 2 by 2 box, which shows your possible offspring, two are Tt (heterozygous) and two are tt (homozygous). The ratio is 2:2, which is the same as 1:1.
2) For homozygous alleles, you can either have homozygous dominant or recessive. Usually the problem tells you which allele is dominant, but the dominant allele is usually shown with a capital letter, or T in this problem! That means homozygous dominant is two capital T's, TT, and homozygous recessive is two lowercase t's, or tt. We will be looking for how many are homozygous recessive, or tt.
Looking at the 2 by 2 box, two of the four offspring have the genotype tt. 2/4 = 50%.

Jamie is making a beaded necklace the ratio of blue beads to purple beads is 4:3 if jamie uses 56 blue beads and purple beads to finish her necklace how many of them will be purple
Answers
Explanation
We will use a proportion to solve this.
The ratio of blue to purple beads is 4:3, or 4/3.
We know she uses 56 blue beads and an unknown amount, x, of purple beads. This gives us 56/x.
Together, we have
4/3 = 56/x
Cross multiply:
4*x = 3*56
4x = 168
Divide both sides by 4:
4x/4 = 168/4
x = 42
Answer: 24 beads
Step-by-step explanation:
Jamie is making a beaded necklace having the ratio of blue beads to purple beads as 4:3 and the total beads used by Jamie is 56. This information can be written as:
Ratio of blue heads= 4
Ratio of purple beads= 3
Total ratio of beads= 4+3 = 7
Total beads used = 56 beads
The number of purple beads used will be= 3/7 × 56
= 3 × 8
= 24 beads
The number of purple beads used is 24

the stem and leaf plot represents a set of data what is the largest number in the set?
Answers
To find the largest number in a stem-and-leaf plot, identify the row with the highest stem and the largest leaf in that row.
The largest number in a set represented by a stem-and-leaf plot can be determined by locating the highest stem value and the largest leaf value attached to it. In a scenario where the stem represents units of 100,000 and the leaf represents units of 10,000, as with the example regarding U.S. cities' populations, you would look for the row with the highest stem number and the highest leaf number within that row to find the largest value. For instance, with a stem of 4 and a leaf of 9, one would interpret the largest number as 490,000.
When constructing a stemplot, each data point's stem is written in a vertical column with the leaves arranged to the right. Negative numbers are handled with negative stems, and the leaves are rounded to represent two significant digits. This method creates a clear visual of data distribution, showing values, potential outliers, and general trends.

The probability of drawing a red marble is 1/8.
The correct option is C.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
We have,
Total marbles = 24
White marble = 6
Blue marble = 8
Black marble = 7
Red marble = 3
So, the probability of drawing a red marble
= 3 / 24
= 1/8

Susan gets paid x dollars per hour. After 40 hours she gets paid time and a half (1.5 times her normal hourly pay). Last month she worked 52 hours each week and earned $696 each week. How much does Susan get paid per hour?
Answers
Let x be the amount she gets paid per hour. Working 40 hours would then be represented by 40x.
Anything over 40 hours earns her 1.5 her normal rate, or 1.5x. Since she works 52 hours, this means 52-40=12 hours of overtime at 1.5x:
12(1.5x) = 18x
Together, she earned 696:
40x+18x = 696
Combining like terms,
58x = 696
Divide both sides by 58:
58x/58 = 696/58
x = 12

3x-4 = 3(13) -4 = 39-4 = 35
2x+9 = 2(13)+9 = 26+9 = 35
the angles = 35 degrees
9=3x-2x-4
9=x-4
