Answer:
50%
Step-by-step explanation:
We are given that four o'clock flower is an example of incomplete dominance
Rt=Red
r=white
Rr=Pink
We have to find the chances that an offspring will have pink flowers when two hybrids are crossed.
When Rr crossed with Rr
Then we get RR,Rr,Rr and rr.
Color of RR=Red
Color of white =White
Color Rr =Pink
Chances of RR=25%
Chances of Rr=50%
Chances of rr=25%
Hence, the chances that an offspring will have pink color=50%
Answer:
The z-statistic for this test is -1.547 and P-value of the test is 0.0618
Step-by-step explanation:
An article in the Washington Post on March 16, 1993 stated that nearly 45 percent of all Americans have brown eyes.
We are given that A random sample of n=82 C of I students found 30 with brown eyes.
n = 82
x = 30

Now to find z statistic we will use one sample proportion test



Formula of test statistic =
=
=
So, the z-statistic for this test is -1.547
Now refer the z table for p value .
p value = 0.0618
The P-value of the test is 0.0618
Hence the z-statistic for this test is -1.547 and P-value of the test is 0.0618
Step-by-step explanation:
Because the sentence is speaking that he has done already so we will use the past verb ran
Rick says he has ran two miles already
Answer: First I suggest that you write out the all the proportions which govern the 3 right triangles involved.
Once you do that you will find this one:
PQ/PS =PR/PQ
PR=PS+SR
Substitution will give you this quadratic:PQ2=PS2+PS*SR
144=PS2+7PS which has only one solution which make sense, namely 9
Then QS=sqrt(144-81)
Step-by-step explanation:
Calculating the sum of 1 through 50: 50 x 51/2 = 25 x 51 = 1275.
