A number, x, rounded to 1 decimal place is 3.7
Write down the error interval for x.
Answer: (3.65, 3.74)
Step-by-step explanation:
Now, when we round a number to a given decimal place, we need to look at the decimal to the left of the decimal place where we are rounding.
if it is 5 or more, we round up
if it is smaller than 5, we round down.
Then for example, if we want to round:
4.534
to the first decimal place, we need to look at the second decimal place.
we can see that it is a 2.
Then we round down, and get:
4.5
Now we know that, when rounding to the first decimal place, we have:
x = 3.7
Then the maximum value that x could have is:
x = 3.74 (because here we round down to 3.7)
and the minimum value that x could have is:
x = 3.65 (because here we round up to 3.7)
Then the error interval for x is:
(3.65, 3.74)

The ratio of dogs to cats in a veterinarian's office is 9:7. What is the ratio of the number of dogs
to the total number of dogs and cats in the veterinarian's office?
Answer:
The ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office is 9:16.
Step-by-step explanation:
Ratio:
The ratio of a to b is given by:
[tex]a:b = \frac{a}{b}[/tex]
The ratio of dogs to cats in a veterinarian's office is 9:7.
This means that for each 9 dogs, there are 7 cars.
What is the ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office?
9 dogs
9 + 7 = 16 dogs and cats. So
The ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office is 9:16.
Jackson bought snacks for his team's practice. He bought a bag of apples for $2.74
and a 10-pack of juice bottles. The total cost before tax was $26.14. How much was
each bottle of juice?
Answer:
each bottle of juice costs $2.34
Step-by-step explanation:
2.74+10x=26.14
10x=26.14-2.74
10x=23.40
x=23.40/10
x=2.34

solve: 2(5x + 3)= 25
solve : 2(5x + 3) = 25
SOLUTION:▶️2(5x + 3) = 25
▶️ 2 × 8x = 25
▶️ 16x = 25
▶️ x = 25/16
▶️ x = 1.5625
ANSWER:1.5625
Step-by-step explanation:
Step 1:
2(5x+3)=25
(2)(5x) + (2)(3)=25 (distribute)
10x+6=25
Step 2:
10x+6 - 6 = 25 - 6
10x =19

35% of students take spainsh or engineering. 30% of students take Spanish. 25% of students take engineering. What is the probability that a student takes Spanish and engineering?
Answer:
0.2 = 20% probability that a student takes Spanish and engineering
Step-by-step explanation:
We solve this question treating the probabilities as Venn sets.
I am going to say that:
Event A: Student takes Spanish
Event B: Student takes Engineering.
35% of students take spainsh or engineering.
This means that [tex]P(A \cup B) = 0.35[/tex]
30% of students take Spanish.
This means that [tex]P(A) = 0.3[/tex]
25% of students take engineering.
This means that [tex]P(B) = 0.25[/tex]
What is the probability that a student takes Spanish and engineering?
This is [tex]P(A \cap B)[/tex].
These probabilities are related by the following formula:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
So
[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B)[/tex]
Replacing the values
[tex]P(A \cap B) = 0.3 + 0.25 - 0.35 = 0.2[/tex]
0.2 = 20% probability that a student takes Spanish and engineering

5/6
of 12 =
Answer: 10
Step-by-step explanation: (5/6) times 12
Answer:
10
Step-by-step explanation:
[tex]\frac{5}{6}[/tex] × [tex]\frac{12}{1}[/tex]
Multiply 12 times 5 to get 60. Then, multiply 6 times 1 to get 6.
Lastly, divide 60 by 6, which equals 10.
Solve (x - 2)^2 - 3 = 1 graphically. That is graph y = (x - 2)^2 - 3 and y = 1 on the same set of axes and find the x-value(s) of any points of intersection. Then use algebraic strategies to solve the equation and verify that your graphical solutions are correct.
Check the attachment(s) for the graphs pertaining to the question
No. 1) Check graph [first attachment]
No. 2) y = (x - 2)^2 - 3, y = 1
(x - 2)^2 - 3 = 1,
(x - 2)^2 = 4
x - 2 = √4, x - 2 = - √4
x = 4, x = 0
Substitute back to determine the respectively y-value:
y = (4 - 2)^2 - 3 = (2)^2 - 3 = 4 - 3 = 1
Check: y = (0 - 2)^2 - 3 = (-2)^2 - 3 = 4 - 3 = 1
So the points of intersection are (4, 1) and (0, 1). According to the graph, that is correct.
Please help me!!!!!!!!!!!!!!
find the inequality represented by the graph
Answer:
y is greater than or equal to -2x-5
Step-by-step explanation:
First find the slope which is -2x and then find the y-intercept which is -5 and then you can just test out if its greater than or equal to, or less than or equal to. To do this you just fill in the point 0,0 and if you do that you should get 0 is greater than (you can ignore the "or equal to") -5 and is that true? Yes it is! so then the side of the line that the point 0,0 is on should be shaded and since it is your answer is right!

Answer:
8
Step-by-step explanation:
So first do 104+76+104=284
Now form the equation 10x-4+284=360
It is 360 because this is a quadrilateral.
Now combine like terms.
10x+280=360
10x=80
x=8
Check 80-4=76
