The Punnett square below shows the cross between two parents heterozygous for two traits. In horses, the allele for black color (B) is dominant over the allele for white color (b). Long hair (H) is
dominant over the short hair (h).
1. What are the genotype and phenotype of the offspring in block A, B, C, D, and E?
2. What is the probability of getting a black horse with short hair?
Genotype
Phenotype
A
B
с
D
E
See the attached table of genotypes.
A black horse with short hair has genotype Bxhh, where the x can be either B or b. According to the table, 3 of the 16 possible genotypes match this pattern, so the probability is 3/16.
A landscaping company placed two orders with a nursery. The first order was for 13 shrubs and 4 trees and totaled 487. The second order was for 6 scrubs and 2 trees,and totaled 232. The bills do not list the per-item price. What were the costs of one shrub of one tree?
Answer:
Cost of shrubs = 23
Cost of tree = 47
Step-by-step explanation:
Let
Cost of shrubs = x
Cost of tree = y
13x + 4y = 487 (1)
6x + 2y = 232 (2)
Multiply (2) by 2
12x + 4y = 464 (3)
13x + 4y = 487 (1)
Subtract (3) from (1)
13x - 12x = 487 - 464
x = 23
Substitute x = 23 into (2)
6x + 2y = 232 (2)
6(23) + 2y = 232
138 + 2y = 232
2y = 232 - 138
2y = 94
y = 94/2
= 47
y = 47

Show the different measuring instruments to be used in the economic/business system of the new civilization.
Answer:
The different measuring instruments to be used in the economic/business system of the new civilization is discussed below in detail.
Step-by-step explanation:
Economics is the research of how people allocate limited resources for generation, circulation, and consumption, both personally and collectively.
Two significant types of economics are microeconomics, which concentrates on the performance of individual customers and generators, and macroeconomics, which measures overall economies on a local, nationwide, or global scale.
Economics is especially concerned with performance in generation and exchange and practices models and opinions to assume how to generate incentives and procedures that will maximize productivity.
Economists formulate and announce numerous economic symbols, such as the Consumer Price Index (CPI). and gross domestic product (GDP).
Capitalism, communism, and socialism are examples of economic systems.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Big Phone Company:
Cost after 4 minutes.
= 0.39 + 4 x 0.03
= 0.39 + 0.12
= $0.51
LittlePhone Company
Cost after 4 minutes.
= 0.25 + 4 x 0.07
= 0.25 + 0.28
= $0.53
Thus,
The Big Phone Company charges less as compared to the LittlePhone Company after using it for 4 minutes.

what are the steps for solving
6x-1=-x+9
Answer:
x=10/7
Let's solve your equation step-by-step
6x−1=−x+9
Step 1: Add x to both sides
6x−1+x=−x+9+x
7x−1=9
Step 2: Add 1 to both sides
7x−1+1=9+1
7x=10
Step 3: Divide both sides by 7
7x/7=10/7
x=10/7
Answer:
x = 10 / 7
Step-by-step explanation:
6x - 1 = -x + 9
Add 1 to both sides of the equation.
6x - 1 = -x + 9
6x - 1 + 1 = -x + 9 + 1
Simplify
Add the numbers
6x - 1 + 1 = -x + 9 + 1
6x = -x + 9 + 1
Add the numbers
6x = -x + 9 + 1
6x = -x + 10
Add x to both sides of the equation.
6x = -x + 10
6x + x = -x + 10 + x
Simplify
Combine like terms
6x + x = -x + 10 + x
7x = -x + 10 + x
Combine like terms
7x = -x + 10 + x
7x = 10
Divide both sides of the equation by the same term
7x = 10
7x/7 = 10/7
Simplify
Cancel terms that are in both the numerator and denominator.
7x/7 = 10/7
x = 10/7
Solution
x = 10/7

Answer:
1a) 67.2 kg
1b) 66.5 kg
1c) 64 kg, 68 kg
2a) Mean = 58.1m, Median = 55m, Mode = 49m
2b) The mode is not a good measure since all data except 49m appeared twice i.e. the data set is quite distributed. (sorry I am not very sure with this answer)
3a) Independent variable is time, Dependent variable is distance.
3b) See attachment.
3c) Linear
3d) 2.5s: 10m 6.25s: 25m 8s: 32m
3e) 3m: 0.75s 21m: 5.25s. 36m: 9s.
Step-by-step explanation:
1a) Mean = (74+71+68+84+54+60+64+68+65+64)/10 kg = 67.2 kg
1b) Sort the data in ascending order (in kg).
54 60 64 64 65 68 68 71 74 84
Median = (65+68)/2 kg = 66.5 kg
1c) Mode = 64 kg, 68 kg (both appeared twice)
2a) Mean = (45+52+47+55+62+80+71+60+84+57+46+50+48+61+49+63+54+49+72)/19 m = 58.1m (correct to 1 decimal place)
Arrange the data in ascending order (in m).
45 46 47 48 49 49 50 52 54 55 57 60 61 62 63 71 72 80 84
Median = 55m
Mode = 49m (appeared twice)
2b) See answer.
3a) Independent variable is the variable that is to be changed. Dependent variable is the variable that is to be measured.
3b) Just plot the graph.
3c) Distance = 4 x time
3d) 2.5 x 4 = 10m. 6.25 x 4 = 25m. 8 x 4 = 32m.
3e) 3/4=0.75s. 21/4=5.25s. 36/4=9s.

Pumpkins pounds and weight
Step-by-step explanation:
Answer: Percy decided to weigh different numbers of pumpkins to find their weights. He put his findings in the table above (in he question) . He found a pattern in his findings, so he used it to find how many 50 pumpkins will weigh. Can you tell me what answer he got?
Step-by-step explanation:
Since every 5 pumpkins is 8 pounds, we just need to divide 50 by 5, and times that number by 8 pounds to find the answer.
50/5 is 10.
10 x 8 = 80
Or, since 25 are 50 pounds, and 25 +25 = 50, you ad 40 to 40, giving you the answer 80.
The answer to my word problem is 80.

Pedro drives the same route to work on Monday through Friday. His route includes one traffic light. According to the local traffic department, there is a 55% chance that the light will be red when he arrives at the intersection on a randomly selected workday. Suppose we choose 10 of Pedro's workdays at random and let Y = the number of times that the light is red.
Answer:
6 days
Step-by-step explanation:
Given
The proportion can be represented as:
[tex]p = 55\%[/tex]
And the number of days can be represented as:
[tex]n = 10[/tex]
Required
Determine the expected number of times, the light is red
To do this, we simply multiply the proportion by the number of days:
[tex]Y = n * p[/tex]
Substitute values for n and p
[tex]Y = 10 * 55\%[/tex]
Convert percentage to decimal
[tex]Y = 10 * 0.55[/tex]
[tex]Y = 5.5[/tex]
Approximate
[tex]Y = 6[/tex]
Hence, the expected number of days is 6 days
If "u" varies directly with "v", and u = 6 when v = -7, what is "u" when v =4?
Answer:
u = -24/7
Step-by-step explanation:
u = 6 = u
v -7 4
-7u = 24
u = -24/7
Answer:
u = - [tex]\frac{24}{7}[/tex]
Step-by-step explanation:
Given that u varies directly with v then the equation relating them is
u = kv ← k is the constant of variation
To find k use the condition u = 6 when v = - 7, then
6 = - 7k ( divide both sides by - 7 )
- [tex]\frac{6}{7}[/tex] = k
u = - [tex]\frac{6}{7}[/tex] v ← equation of variation
When v = 4 , then
u = - [tex]\frac{6}{7}[/tex] × 4 = - [tex]\frac{24}{7}[/tex]

A line passes through (-2,5) and has slope 1/3. what is an equation of the line in point-slope form?
Answer:
y = 1 3 x + 13 3
Step-by-step explanation:
The equation of the line is
y = 1 3 x + 13 3
. To find other points on the line, simply plug in an x value, and solve for the corresponding y value.
Explanation:
To find other points on the line, we first have to find the equation for the line. We can easily use point-slope form:
y − y 1 = m ( x − x 1 )
y − 5 = 1 3 ( x 2 )
To put it in slope-intercept form, isolate y and simplify:
y= 1 3 ( x − 2 ) + 5
y = 1 3 x − 23 + 5
y = 1 3 x + 13 3
