The price of two tubes of toothpaste after Allie uses the coupon is $1.93.

To calculate the price of two tubes of toothpaste after Allie uses the coupon, we can use the following steps:

Calculate the price of two tubes of toothpaste without the coupon.

Subtract the value of the coupon from the price of two tubes of toothpaste without the coupon.

Step 1: Calculate the price of two tubes of toothpaste without the coupon.

The price of one tube of toothpaste is $1.39, so the price of two tubes of toothpaste is:

$1.39/tube * 2 tubes = $2.78

Step 2: Subtract the value of the coupon from the price of two tubes of toothpaste without the coupon.

The value of the coupon is $0.85, so the price of two tubes of toothpaste after Allie uses the coupon is

$2.78 - $0.85 = $1.93

Therefore, the price of two tubes of toothpaste after Allie uses the coupon is $1.93.

Final answer:

The question asks for the ratio of yellow eggs to colored eggs, which is 10 yellow eggs to 12 colored eggs. Simplifying the ratio, we get 5:6. This concept of ratios is also seen in Mendel's genetic experiments with plants, where traits are passed in specific ratios like 3:1.

Explanation:

In mathematical terms, a student's question regarding the ratio of yellow eggs to the total number of colored eggs can be answered using simple division to derive a fraction or ratio. Given that there are 10 yellow eggs out of 12 colored eggs, the ratio can be expressed as 10:12.

However, ratios should be simplified to their smallest form to be more understandable; therefore, this ratio simplifies to 5:6 since both numbers can be divided by 2.

When looking at historical experiments, such as the ones conducted by Mendel, we find that phenotypic ratios play a significant role in understanding genetics. Mendel observed that traits could manifest in a specific ratio, like a 3:1 ratio for dominant to recessive traits. The ratios observed in the experiments provided can serve as examples to understand how ratios represent the occurrence of certain outcomes over others.

In this case, the ratio of yellow to green seeds in Mendel's experiment can serve as an analogy to understand the ratio of yellow eggs: both ratios quantitatively describe the presence of a certain characteristic compared to another.

The vertical distance is 25.825 ft

Step-by-step explanation:

we know that

To find out the vertical distance between Cece and the base of the mountain, subtract the height of the base of the mountain from the height of Cece

Let

x -----> the height of Cece

y ----> the height of the base of the mountain

we have

[tex]x=15\frac{5}{8}\ ft[/tex] ----> is positive because is above sea level

convert to an improper fraction

[tex]x=15\frac{5}{8}\ ft=\frac{15*8+5}{8}=\frac{125}{8}=15.625\ ft[/tex]

[tex]y=-10.2\ ft[/tex] -----> is negative because is below sea level

Answer:

Ian need to keep the website for site B less than 10 months

Step-by-step explanation:

Let

x -----> the number of months

y ----> the cost for website hosting

we know that

Site A

[tex]y=4.95x+49.95[/tex] -----> equation A

Site B

[tex]y=9.95x[/tex] -----> equation B

Equate equation A and equation B and solve for x

[tex]9.95x=4.95x+49.95[/tex]

[tex]9.95x-4.95x=49.95[/tex]

[tex]5x=49.95[/tex]

[tex]x=9.99\ months[/tex]

Round the number of months

[tex]x=10\ months[/tex]

For x=10 months ----> the cost for website hosting is the same in both sites

For x>10 months ---> the cost for website hosting is less expensive in site A

For x<10 months ---> the cost for website hosting is less expensive in site B

therefore

Ian need to keep the website for site B less than 10 months

When comparing the two hosting sites, Site B becomes cheaper than Site A after around 10 months, if the website is kept active during this period. This calculation is made by setting up an equation for the costs and solving for the number of months.

When Ian wants to promote his band on the Internet by creating a website, he needs to make a decision about the cost effectiveness between the two hosting sites. Let's break down the costs for each site:

To find out when Site B would be cheaper than Site A, we need to set up an equation where the left-hand side is the cost for Site A and the right-hand side is the cost for Site B. The equation would therefore be, $49.95 + $4.95n (with n being the number of months) = $9.95n.

To solve for n, subtract $4.95n from both sides leaving $49.95 = $5n. Dividing $49.95 by $5 gives us n = 9.99, which means after around 10 months, Site B becomes cheaper than Site A provided Ian keeps the site active.

Probability of a male having a blood circulation problem, given he's a smoker, is approximately 0.6667.

Step 1:

Identify the given probabilities:

Let [tex]\( P(A) \)[/tex] be the probability that a randomly chosen male has a blood circulation problem, which is [tex]\( 0.25 \)[/tex].

Let [tex]\( P(B|A) \)[/tex] be the probability that a male is a smoker given that he has a blood circulation problem, and it's twice the probability of being a smoker given not having a blood circulation problem.

Step 2:

Calculate [tex]\( P(B|\neg A) \)[/tex]:

Since males with blood circulation problems are twice as likely to be smokers as those without, \( P(B|\neg A) \) is half of [tex]\( P(B|A) \)[/tex], which is [tex]\( \frac{1}{2} \)[/tex].

Step 3:

Apply Bayes' theorem:

[tex]\[ P(A|B) = \frac{P(B|A) \times P(A)}{P(B)} \][/tex]

Step 4:

Calculate \( P(B) \):

[tex]\[ P(B) = P(B|A) \times P(A) + P(B|\neg A) \times P(\neg A) \][/tex]

Step 5:

Substitute values into Bayes' theorem and solve:

[tex]\[ P(A|B) = \frac{(2 \times P(B|\neg A)) \times P(A)}{(2 \times P(B|\neg A)) \times P(A) + P(B|\neg A) \times (1 - P(A))} \]\[ P(A|B) = \frac{(2 \times \frac{1}{2}) \times 0.25}{(2 \times \frac{1}{2}) \times 0.25 + \frac{1}{2} \times (1 - 0.25)} \]\[ P(A|B) = \frac{0.25}{0.25 + 0.125} \]\[ P(A|B) = \frac{0.25}{0.375} \]\[ P(A|B) \approx 0.6667 \][/tex]

Thus, the probability that a male has a blood circulation problem, given that he is a smoker, is approximately 0.6667.

C. [tex]x=\frac{5}{2}[/tex]

Step-by-step explanation:

The quadratic formula is:

[tex]x_{1,2}=\frac{-b\±\sqrt{b^{2}-4ac}}{2a}[/tex]

Where [tex]a[/tex] is the coefficient of the quadratic team. [tex]b[/tex] is the coefficient of the linear term, and [tex]c[/tex] is the independent term.

So, the given equation is:

[tex]x^2 - 5x + \frac{25}{4}  = 0[/tex]

Where:

[tex]a=1\\b=-5\\c=\frac{25}{4}[/tex]

[tex]x_{1,2}=\frac{-(-5)\±\sqrt{(-5)^{2}-4(1)(\frac{25}{4} )}}{2(1)}\\x_{1,2}=\frac{5\±\sqrt{25-25}}{2}\\x_{1,2}=\frac{5\±\sqrt{0}}{2}\\x_{1,2}=\frac{5}{2}[/tex]

This means that the equation has a unique solution.

Therefore, the right answer is C.
