Tito purchased sandwiches and a gallon of milk for himself and his friends. Each
sandwich cost $9. The gallon of milk cost $6. The total cost of the meal was $33.
Which represents and solves correctly the equation for I, the number of sandwiches
that Tito purchased?
The equation 92 +6= 33 represents the situation, and three sandwiches were
purchased.
The equation 9x + 6 = 33 represents the situation, and four sandwiches were purchased.
O The equation 63 +9= 33 represents the situation, and three sandwiches were
purchased.
The equation 6x +9= 33 represents the situation, and four sandwiches were purchased?
Answer:
The equation 9x + 6 = 33 represents the situation, and three sandwiches were purchased.
Step-by-step explanation:
Each sandwich cost $9.
The gallon of milk cost $6.
The total cost of the meal was $33.
Let us represent the number of sandwiches that Tito bought as x
The equation is:
$9 × x + $6 = $33
9x + 6 = 33
Collect like terms
9x = 33 - 6
9x = 27
x = 27/9
x = 3
Hence,
The equation 9x + 6 = 33 represents the situation, and three sandwiches were purchased.
The quotient of 5 divided A is great than, less than or equal to the quotient of A divided 5?
Answer:
It will depend
Step-by-step explanation:
If a<5 then quotient of 5 divided A is greater than the quotient of A divided 5.
If a=5 then quotient of 5 divided A is equal to the quotient of A divided 5.
If a>5 then quotient of 5 divided A is less than the quotient of A divided 5.
Find the value of x 105 150 135 125 140 135 x
By using the fact that the sum of the interior angles is 900°, we will find that the value of x is 110.
How to find the value of x?We know that for a figure of N sides, the sum of the interior angles gives:
S = (N - 2)*180°
In this case, we have 7 sides, then the sum of the interior angles gives:
S = (7 - 2)*180° = 5*180° = 900°
Adding the 7 angles we get:
105° + 150° + 140° + x° + 135° + 125° +135° = 900°
790° + x° = 900°
x° = 900° - 790°
x = 110°
The value of x is 110.

I said SAS but am not sure because the base could be two equal sides as well so could someone help me out?
Answer: C) SAS is correct
Check out the diagram below.
We're given BA = BC as shown in red.
The congruent angles are shown in blue. The larger angle is bisected into smaller equal halves.
The red segments are congruent by the reflexive property.
The angles mentioned are between the sides mentioned, so that's why we can use SAS.

In 2008, there were 507 children in Arizona out of 32,601 who were diagnosed with Autism Spectrum Disorder (ASD) ("Autism and developmental," 2008). Find the proportion of ASD in Arizona with a confidence level of 99%.
Answer:
The 99% confidence interval for the proportion of ASD in Arizona is (0.014, 0.018).
Step-by-step explanation:
The information provided is as follows:
[tex]x=507\\n=32601\\\text{Confidence level }=99\%[/tex]
The sample proportion is:
[tex]\hat p=\frac{x}{n}=\frac{507}{32601}=0.016[/tex]
The critical value of z for 99% confidence level is, z = 2.56.
Compute the 99% confidence interval for the proportion of ASD in Arizona as follows:
[tex]CI=\hat p\pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]
[tex]=0.016\pm 2.58\cdot\sqrt{\frac{0.016(1-0.016)}{32601}}\\\\=0.016\pm 0.0018\\\\=(0.0142, 0.0178)\\\\\approx (0.014, 0.018)[/tex]
Thus, the 99% confidence interval for the proportion of ASD in Arizona is (0.014, 0.018).
Quick answer please!!!! Brodie hires a technician to fix his air conditioning unit. The total cost includes $26.50 for parts and $50.00 per hour the technician works on the job. Which equation can be used to find y, the total cost Brodie pays, given x represents the number of hours the technician works on the job? y=26.50x−50 y = 26.50x + 50 y = 50x + 26.50 y=26.50(x+50)
Answer:
y = 50x + 26.50
Step-by-step explanation:

If 4% of a number is 8, find 1% of that number.
How do I solve this problem?
Answer:
2
Step-by-step explanation:
First, find the number by dividing 8 by 0.04
8/0.04
= 200
Then, find 1% of 200 by multiplying it by 0.01:
200(0.01)
= 2
So, 1% of the number is 2.
Answer:
The answer is 2
Step-by-step explanation:
4%x5=20% and 8x5=40, 20%x5=100% and 40x5=200 and 1% means you move the decimal to the left twice so it is 2, my explanation might be wrong but I know my answer is correct:

the value of the expression when t-32 degrees is what degrees
Complete Question:
The temperature doubled. Evaluate when t = 32 degrees.
The value of the expression when t = 32 degrees is degrees
Answer:
64 degrees
Step-by-step explanation:
Given
[tex]t = 32[/tex]
Required
Determine the value of t when it doubles
To do this, we simply multiply the current temperature by 2.
So:
[tex]t = 32[/tex] becomes
[tex]t = 32 * 2[/tex]
[tex]t = 64[/tex]
Hence, the temperature when it doubles is 64 degrees

A poll commissioned by Friends of the Earth and conducted by the Mellman Group found that 72% of American voters are in favor a carbon tax. Suppose that six voters in the United States are randomly sampled and asked whether they favor a carbon tax. Determine the probability that the number answering in the affirmative is a. Exactly four. b. At least two
Answer:
a
[tex]P(X = 4) = 0.31599[/tex]
b
[tex]P(X \ge 2) = 0.9921 [/tex]
Step-by-step explanation:
From the question we are told that
The proportion in favor of carbon tax is [tex]p = 0.72[/tex]
The sample size is n = 6
Generally the distribution of poll follows a binomial distribution
i.e
[tex]X \~ \ \ \ B(n , p)[/tex]
and the probability distribution function for binomial distribution is
[tex]P(X = x) = ^{n}C_x * p^x * (1- p)^{n-x}[/tex]
Here C stands for combination hence we are going to be making use of the combination function in our calculators
Generally the probability that the number answering in the affirmative is 4 is mathematically represented as
[tex]P(X = 4) = ^{6}C_4 * (0.72)^4 * (1- 0.72)^{6-4}[/tex]
=> [tex]P(X = 4) = 0.31599[/tex]
Generally the probability that the number answering in the affirmative is At least two is mathematically represented as
[tex]P(X \ge 2) = 1 - P( X < 2 ) [/tex]
[tex]P(X \ge 2) = 1- [ P(X = 0 ) + P( X = 1)] [/tex]
=> [tex]P(X \ge 2) = 1- [ [ 1 * 1 * 0.00048 ]+ [ 6 * 0.72 * 0.00172] [/tex]
=> [tex]P(X \ge 2) = 1- [ 0.00791 ] [/tex]
=> [tex]P(X \ge 2) = 0.9921 [/tex]

B. no meor than three games
Step-by-step explanation:
400.00 - 289.99 = 110.01
110.01 - 32.29 = 72.72 (1 game)
72.27 - 32.29 = 45.43 (2 games)

The following are the last 7 days adjusted closing stock prices (in $) for Citigroup: 22, 25, 20, 15, 40, 55, 28 A) Compute the 25th percentile by hand and interpret. B) Compute the sample mean and median by hand. What is the shape of the data set?
Answer:
(A) The 25th percentile is 20.
(B) The mean of the data set is 20 and the median of the data set is 25. The data set is left-skewed.
Step-by-step explanation:
The data set arranged in ascending order is:
S = {15, 20, 22, 25, 28, 40, 55}
(A)
Compute the 25th percentile as follows:
[tex]25^{th} \text{Percentile}=[\frac{n+1}{4}]^{th}obs.\\\\=[\frac{7+1}{4}]^{th}obs.\\\\=2^{nd}obs.\\\\=20[/tex]
Thus, the 25th percentile is 20. This value implies that exactly 25% of the observations are less than 20.
(B)
Compute the sample mean as follows:
[tex]\text{Mean}=\frac{22+25+20+15+40+55+28}{7}=\frac{205}{7}=29.29[/tex]
Compute the median as follows:
For a set with odd number of observations, the median value if the middle value.
The middle value is 25.
Thus, the mean of the data set is 20 and the median of the data set is 25.
The Mean < Median.
This implies that the data set is left-skewed.

Step 1: Define systems
x = y - 3
2x - 2y = -6
Step 2: Solve for y
Substitute: 2(y - 3) - 2y = -6Distribute 2: 2y - 6 - 2y = -6Combine like terms: -6 = -6Here we see that -6 does equal -6. Therefore, any value y would work as a solution. Hence, this systems of equations has an infinite amount of solutions.
