The frequency for 2 to 7 is 3
The frequency for 8 to 13 is 4
The frequency for 14 to 19 is 2
The grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.
Given that, nine cyclists were each asked the distance in miles they biked last week. The distance travelled by 9 cyclists is 16, 8, 2, 6, 8, 11, 9, 15 and 7.
We need to complete the grouped frequency distribution for the data.
What is the grouped frequency distribution?In this type, the data is arranged and separated into groups called class intervals. The frequency of data belonging to each class interval is noted in a frequency distribution table. The grouped frequency table shows the distribution of frequencies in class intervals.
Now, the frequency distribution for the given intervals is as follows:
That is, for intervals 2 to 7 the frequency is 3.
For intervals 8 to 13 the frequency is 4.
For intervals 14 to 19 the frequency is 2.
Therefore, the grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.

Evaluate when x = -3 and y= -1:
Evaluate when x = 3, y = -3 and z = -2:
Which numerical expression is obtained by substituting x= 2, y= 6,
and z = 3 into the expression shown? x - (y+z)
Evaluate when x = 3, y = 2, and z = 4:
here is the answer: so if x = 3, y =2 and z = 4 then the answer is 3 - (2+4)
The total change in the outdoor temperature over 6 hours was -21°F
What was the mean change in temperature per hour?
₋₋₋₋₋₋₋₋ °F per hour
Answer:
-3.5
Step-by-step explanation:
As there was a total change of -21, that would be the first part of your equation:
-21
As 6 hours had passed and you are trying to find the mean, your equation would now be:
-21 ÷ 6 = ?
Now you can solve the equation, and the answer is -3.5°F per hour.
The mean change in temperature per hour is -3.5 °F.
what is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
The total change in the outdoor temperature over 6 hours was -21°F
So, in one hour the mean change in temperature
= -21/6
= -3.5 °F
Hence, the mean change in temperature per hour is -3.5 °F.

An equation is (4)(25)-300.
To write (4)(25)-300 as an addition equation,
we can break it down into two separate addition equations as follows:
(4)(25) - 300 = (4)(25) + (-300)
To solve this further,
substitute the value 25 x 4 = 100 to the above equation, we get,
= 100 + (-300)
Therefore, the equation in the required form is 100 + (-300).

i dont know how to spell.
Answer:
to Stop anxiety attract
take a deep breath hold it for some time and then relax your body when exhaling
Don't think Brainly is the place to ask but If your not getting enough sleep, that can be why so make sure to SLEEP and take naps at around 1:00pm and Try to wake up at 3:00pm
Aerobic activity can be calming. Avoid caffeine, alcohol and smoking which act as triggers for the attack. Regular physical activity helps in releasing the anxiety.
Easier ways are to breathe slow and deep breathing is the cornerstone of calm. Start by breathing in and out slowly.
Drink more water. Dehydration may affect anxiety in a variety of ways. And raw fruits and vegetables are the best foods for panic attack because they act as antioxidants in your body.

Brandon buys a radio for $48.81 in a state where the sales tax is 7%.
can someone pls help?
Answer:
$48.81 x 0.07 = 3.4167
$48.81 + $3.4167 = $52.2267

The shirt cost $48.81, and the sales tax is 7%. First convert the 7% into a decimal and you get 0.07, and then multiply that to the $48.81. You get left with $3.4167 and then add that to the $48.81 to get $52.2267. But, you have to shorten the numbers to make it look like money by simplifing. So the total is $52.23.
