Answer:
A taco cost $1 while a burrito cost $1.79
Step-by-step explanation:
This may be computed as a set of simultaneous equations
Thelma ordered 2 tacos and 1 burrito and paid $ 3.79
let the cost of a taco be t and a burrito b then
2t + b = 3.79
Louise ordered 2 burritos and 1 taco and paid . \$4.58
t + 2b = 4.58
solve both equations simultaneously
multiply the first by 2
4t + 2b = 7.58
t + 2b = 4.58
subtract 2 from 1
3t = 3
t = 1
t + 2b = 4.58
1 + 2b = 4.58
2b = 4.58 - 1
2b = 3.58
Divide both sides by 2
b = 1.79

11 / 16
Answer:
4.5/16+6/16=4.5+6/16
=10.5/16
Step-by-step explanation:
Here you can see denominator in both the side are same and operation sign between them is plus, therefore you can take denominator as is it.
Then add numerator and divide by denominator which is 16. Answer is 10.5/16 since you have to simplify only.

2. A student measured the mass of an object
to be 56 g, but the actual mass was 53 g.
What is the absolute error?
Quickkkkkk
The absolute Error is 5.66%.
What is absolute Error?The discrepancy between a quantity's measured or inferred value and its actual value is known as the absolute error.
The absolute error is insufficient because it provides no information about the significance of the error. An inaccuracy of a few centimetres when estimating the kilometres between cities is insignificant and unimportant. A measurement mistake of a few centimetres when measuring tiny machine parts is a highly important defect. Although both inaccuracies are in the centimetre range, the second one is more serious than the first.
Given:
Actual Mass = 53g
and, Measure mass= 56 g
So, Absolute Error = | 56- 53 / 56| x 100
Absolute Error = |3 / 56| x 100
Absolute Error = 0.056603 x 100
Absolute Error = 5.66%
Hence, the absolute Error is 5.66%.

A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 23.4 pounds and a standard deviation of 6.8 pounds. Step 1 of 2 : If a sampling distribution is created using samples of the amounts of weight lost by 63 people on this diet, what would be the mean of the sampling distribution of sample means
Answer:
The mean of the sampling distribution of sample means would be of 23.4 pounds.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
What would be the mean of the sampling distribution of sample means?
By the Central Limit Theorem, the population mean, that is, of 23.4 pounds.

a=6^2
a=36
now for the triangles
a= height of triangle * base/ 2
a= 12*6/2
a= 36
and since there is 4 of the triangles we multiply 36 by 4

C. $(x) - 2032(0.85)
B. $(x) - 2032(1.85)
D. f(x) – 2032(0.15)
Answer:
Step-by-step explanation:
The Answer will be D hope this helps ya :)
The function representing the number of bacteria present each day is
[tex]\rm f(t) = 2032(0.85)^{t}[/tex] .
What is a function ?
A function from a set X to a set Y assigns to each element of X exactly one element of Y.
The set X is called the domain of the function and the set Y is called the codomain of the function
A bacteria population starts at 2032 and decrease by 15% everyday.
a function representing the number of bacteria present each day
[tex]\rm f(t) = 2032(1-.15)^{t}[/tex]
[tex]\rm f(t) = 2032(0.85)^{t}[/tex]
Therefore [tex]\rm f(t) = 2032(0.85)^{t}[/tex] is the correct answer .

jamals lawn service often fertilizes lawn in the spring. jamal charges 3.50 per square yard. how much will jamal charge to fertilize the yard pictured below
Answer:
He will charge $28.
Step-by-step explanation:
We know that Jamal charges $3.50 per square yard.
Now we need to find the area in the image, it may be kinda hard to see it, but we can think of the image as a rectangle of 4yd by 3yd where we subtracted the area of a square of side length equal to 2yd.
The area of the rectangle is:
A = 4yd*3yd = 12 yd^2
And the area of the square is:
a = (2yd)^2 = 4 yd^2
The area of our image (equal to the difference between the area of the rectangle and the area of the square) is:
Area = A - a = 12 yd^2 - 4 yd^2 = 8 yd^2
Area = 8 yd^2
And he charges $3.50 per square yard, then for 8 square yards he charges 8 times that amount, which is:
C = 8*$3.50 = $28
