Answer:
-9
Step-by-step explanation:
Here we use the slope formula: m= y2-y1/x2-x1. We simply plug in the numbers we know: -1/10 = -5+6/t-1. Then we solve for t. Multiply both sides by (t-1) so -1/10 (t-1)= 1. Then multiply both sides by -1/10 so t-1= -10 and then add one to both sides so t=-9.
erica planted 8 cucumber plants each plant had 37 green cucumbers. how many cucumbers are the 8 plants altogether
Answer:

A poll is taken to see which candidate students will elect as class president. 43% of
students say they will vote for Alessandra. The poll has a margin of error of 3%, so the
least and greatest percent she could receive is represented by la – 431 = 3, where a is
the actual percent of students that vote for Alessandra. What is the lowest percentage of
votes she could receive?
Answer:
The lowest percentage of votes she could receive is 40%
Step-by-step explanation:
43% of students say they will vote for Alessandra, with a margin of error of 3%.
This means that between 43% - 3% = 40% and 43% + 3% = 46% of the students will vote for Alessandra.
This means that the lowest percentage of votes she could receive is 40% and the highest is 46%.

At this weekend’s football game, 15 out of the first 50 people who entered the field were not wearing hats. If this sample is representative of the 250 people attending the game, about how many of them will probably NOT be wearing hats?
75 people out of 250 will NOT be wearing hats.
At this weekend's football game, 15 out of the first 50 people entered in the field were not wearing hats.
The number of people attending the game is 250.
What is Probability?
Probability is a measure of the likelihood of an event to occur.
Now,
Probability for not wearing hats;
⇒ 250/ 50 = 5
⇒ 15 x 5 = 75
Hence, 75 people out of 250 will NOT be wearing hats.

The events red and black
The events white and two door
The events white and other
The events black and truck

Answer:

Step-by-step explanation:
EDG 2020-2021 Stats
The events ,The events red and black ,The events white and other, The events red and other are mutually exclusive.
What is probability?The probability is defined as the chances of happening any event. Mutually exclusive events are those in which the one event is independent of the other event.
The condition for the mutually exclusive event will be:
[tex]P(A|B)=\dfrac{P(A) \ and P(B)}{P(A)}=P(A)[/tex]
We have the data
red, 0.28
black, 0.30
white, 0.22
other 0.20
Here we will check the mutually exclusive event:-
(1)The events red and black
[tex]P(R|B)=\dfrac{P(R\ and\ B)}{P(B)}[/tex]
[tex]P(R|B)=\dfrac{0.28\times 0.30}{0.30}=0.28 =P(R)[/tex]
Hence the event is exclusive.
(2)The events white and other
[tex]P(W|O)=\dfrac{P(W\ and\ O)}{P(O)}=P(W)[/tex]
[tex]P(W|O)=\dfrac{ 0.22\times 0.20}{0.20}=0.22=P(W)[/tex]
Hence the event is exclusive.
(3) The events red and other
[tex]P(R|O)=\dfrac{P(R\ and\ O)}{P(O)}=P(R)[/tex]
[tex]P(R|O)=\dfrac{ 0.28\times 0.20}{0.20}=0.28=P(R)[/tex]
Hence the event is exclusive.
Hence the events ,The events red and black ,The events white and other, The events red and other are mutually exclusive.

Find the median of these numbers:4,2,7,4,3 *
Answer:
4
Step-by-step explanation:
median: the middle value. to find this, arrange your numbers in order from least to greatest and find the one in the middle. if there are two in the middle, add them and then divide by 2.
4, 2, 7, 4, 3 → 2, 3, 4, 4, 7
since 4 is in the middle, that is your answer
The median of the sequence is 4.
What is the median?One of the three methods of measuring central tendency is the median. The centre point of a data set is indicated while describing it. The measure of central tendency is this. The mean, median, and mode are the three most popular methods for calculating central tendency.
Given the sequence 4,2,7,4,3,
to find median arrange the values in ascending order,
2, 3, 4, 4, 7
since the sequence has 5 digits so the median is the middle term,
center digit is 4,
median is 4.
Hence the median is 4

Jeffrey has an aquarium in the shape of a rectangular prism. He is going to place a layer of sand over the base for his iguana. The area of the base of the aquarium can be represented by the expression (42x3−14x2+21x) feet3. If the width of the aquarium is represented by the expression (7x) feet, what is the length of the aquarium?
Answer:
[tex]Length = 6x^2 - 2x + 3[/tex]
Step-by-step explanation:
Given
[tex]Area = 42x^3 - 14x^2 + 21x[/tex]
[tex]Width = 7x[/tex]
Required
Determine the length of the aquarium
The area of a rectangular base is calculated as:
[tex]Area = Length * Width[/tex]
Substitute values for Area and Width
[tex]42x^3 - 14x^2 + 21x = Length * 7x[/tex]
Make Length the subject
[tex]Length = \frac{42x^3 - 14x^2 + 21x}{7x}[/tex]
Factorize the numerator
[tex]Length = \frac{7x(6x^2 - 2x + 3)}{7x}[/tex]
[tex]Length = 6x^2 - 2x + 3[/tex]
