Sandra orders a box of cube-shaped beads. The beads are neatly stacked in layers, with the same number of beads in each layer. Each layer is12 beads across and 7 beads wide. There are 4 layers. How many beads does she receive
Answer: 336 beads
Step-by-step explanation:
To find how many beads are in each layer, use the equation 12 x 7 = 84
Then multiply the amount of beads by each layer: 84 x 4 = 336

Answer: 1.75 or 1 3/4
Step-by-step explanation:
Because first you need to get R by it’s self by dividing it by 1/2 then if you divided it by one side you have to divide it by the other side so you get r=1.75 or 1 3/4.

A botanist has developed a new hybrid cotton plant that can withstand insects better than other cotton plants. However, there is some concern about the germination of seeds from the new plant. To estimate the probability that a seed from the new plant will germinate, a random sample of 3000 seeds was planted in warm, moist soil. Of these seeds, 2470 germinated.
a. Use relative frequencies to estimate the probability that a seed will germinate. What is your estimate?
b. Use relative frequencies to estimate the probability that a seed will not germinate. What is your estimate?
c. Either a seed germinates or it does not. What is the sample space in this problem? Do the probabilities assigned to the sample space add up to 1? Should they add up to 1? Explain.
1. Yes, because they cover the entire sample space.
2. Yes, because they do not cover the entire sample space.
3. No, because they cover the entire sample space.
d. No, because they do not cover the entire sample space.
d. Are the outcomes in the sample space of part (c) equally likely?
Answer:
a. The estimate of the probability that a seed will germinate is:
82% (0.82)
b. The estimate of the probability that a seed will not germinate is:
18% (0.18)
c. The sample space is 2.
1. Yes, because they cover the entire sample space. The probabilities assigned to the sample space add up to 1 (0.82 +0.18).
They should always add up to one. Probability summed cannot exceed 1.
Step-by-step explanation:
a) Data and Calculations:
Sample = 3,000 seeds
Germinated seeds = 2,470
Non-germinated seeds = 530 (3,000 - 2,470)
Probability of a seed germinating = 2,470/3,000 = 82% approx.
Therefore, the probability of a seed not germinating = 18% (100 - 82) or (530/3,000)
A community college has a math placement exam that has a mean of 65 and a standard deviation of 8.2. If a student takes the exam and scores in the lower 2.5%, they are eligible for a free intensive course to help them succeed in their math class. Assume that the exam has a normal distribution. What is the score that cuts off the bottom 2.5%
Answer:
The score that cuts off the bottom 2.5% is 48.93.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 65, \sigma = 8.2[/tex]
What is the score that cuts off the bottom 2.5%
This is X when Z has a pvalue of 0.025, so X when Z = -1.96.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.96 = \frac{X - 65}{8.2}[/tex]
[tex]X - 65 = -1.96*8.2[/tex]
[tex]X = 48.93[/tex]
The score that cuts off the bottom 2.5% is 48.93.
The price of a mountain bike is $50 more than a road bike. If 4 road bikes and 3 mountian bikes coat $4700. Find the price of a road bike and a mountain bike.
9514 1404 393
Answer:
road bike: $650mountain bike: $700Step-by-step explanation:
If r is the cost of a road bike, then the cost of a mountain bike is r+50. The total cost of the 7 bicycles is ...
4r +3(r+50) = 4700
7r +150 = 4700 . . . . . . eliminate parentheses
7r = 4550 . . . . . . . . . . . subtract 150
r = 650 . . . . . . . . . . . . . divide by 7; price of a road bike
r+50 = 700 . . . . price of a mountain bike
The price of a road bike is $650; the price of a mountain bike is $700.
Find the volume of a cube if an edge has length 4rst units
Answer:
64
Step-by-step explanation:
4 * 4 * 4 = 64
The volume of the cube is [tex]64[/tex]
Given that,
The length of an edge is 4rst.We know that
The volume of the cube is
= side^3
= 4^3
= 64
Therefore we can conclude that the volume of the cube is 64.

Determine if the function is a polynomial function. If the function is a polynomial function, state the degree and the leading coefficient. If the function is not a polynomial, state why. f(x)=(x+1)^1/2(x+2)
It is not a polynomial because there is a fractional exponent.
The surface area of this sphere is 20,096 square centimeters. What's the volume of this sphere please help me
Answer:
Step-by-step explanation:
The trick is to find the radius. The surface area does that.
A =4* pi * r^2
20096 = 4 * 3.14 * r^2
20096 / 4 = 3.14 * r^2
5024 = 3.14 * r^2
5024 / 3.14 = r^2
r^2 = 1600
√r^2 = √1600
r = 40
Now all you do is use r to find the Volume
V = (4/3) * 3.14 r^3
V = (4/3) * 3.14 * 40^3
V = 1.333 * 3.14 * 64000
V = 26796.67

What are the constants in the expression 7r - 3 + 2s + 5
A 7, 3, 2, and 5
B -3 and 5
C 7 and 2
D 7, 2, and 5
Answer:
Option BStep-by-step explanation:
Definition of constants: Contants are numbers that have no variables.
To find the constants of the expression 7r - 3 + 2s + 5, simply look for numbers without variables. We can see that the constants are -3 and 5, which matches Option B.
Hence, Option B is correct.
