The regression equation is:

y = 1.15 – 0.251 x₁ + 0.078 x₂ + 0.306 x₁x₂

<span> <span> <span> Where,
x₁ = -0.2508
x₂ = 0.0777
x₁x₂ = 0.3058

Inserting the values,
<span><span></span></span>y = 1.15 – {0.251 × (-0.2508)} + {0.078 ×(0.0777)} + {0.306 × (0.3058)}
</span></span></span>
y = 1.15 - (- 0.0629508) + 0.0060606 + 0.935748

y = 1.15 + 0.0629508 + 0.0060606 + 0.935748

y = 1.3125862

Answer:

x₁ and x₂ are main effects (a type of tuna and type of packing liquid) that contribute significant information for the prediction of <span>y.</span>

Why are the seminal vesicles important for human reproduction?

This might help:

The seminal vesicles (Latin: glandulae vesiculosae), vesicular glands, or seminal glands, are a pair of simple tubular glands posteroinferior to the urinary bladder of some male mammals. Seminal vesicles are located within the pelvis. They secrete fluid that partly composes the semen.

They pass through the prostate, and open into the urethra at the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the urinary meatus.

I believe that the answer is:

A. 

They allow the sperm to travel to the urethra to be released.

emmainna [20.7K]
They all have the disease. However, carriers are generally consider those who can give the disease, but don’t have it themselves. This would make the answer Lisa and Monica as they have the recessive gene, but only have one allele, meaning they carry the gene for color blindness, but fortunately do not have it due to the dominant allele being normal.

Newsweek in 1989 reported that 60% of young children have blood lead levels that could impair their neurological development. As
Kamila [148]

Answer:

The answer is 83.38%.

Explanation:

The probability of young children having blood levels that impair their neurological development is given as 60% in the question. To find the probability of at least 5 children out of 10 in a sample having said blood levels, we need to use the binomial probability.

n represents the total number of children in the sample so n = 10 and p is the probability of the children having blood levels causing the problem which is 60% so p = 0.6.

We want the probability of it being observed for 5 or more children and that is P(x\geq 5). If we subtract the P( x\leq 4) from 1, which is the probability of not observing the condition in 5 or more children, we will have the P(x\geq 5).

1 - P(x\leq 4) = 1 - pbinom(4, 10, 0.6) which are the probability range in the function, the sample size and the probability of observing the condition respectively.

The result is 1 - 0.1662 = 0.8338 which means that the probability that is asked is 83.38%.

I hope this answer helps.
