Answer:
Number of days starting from T are:-
Tuesday
Thursday
So, number = 2
Number of days in a week = 7
So, probability = 2/7
Hope it helps...!!!
Step-by-step explanation:
Use the equation to
y=2x
7
Answer:
Slope = 2/7
y-intercept = 0
Proportional = yes
It is proportional since we require no additional terms to get y from x and we can multiply each x term by a certain factor to get the y values
Step-by-step explanation:
Generally, we have the equation of a straight line as;
y = mx + b
where m is the slope and b is the y-intercept
From what we can see, the slope of the given line is 2/7
As we can see, there is no y-intercept; so the y-intercept value is 0
As we can see, we can multiply each x value by 2/7 to get the corresponding y-value
What this mean is that both variables are proportional
The calculator command normalcdf returns the _______ that a randomly selected value falls in a given reigon of a normal probability
Answer:
The percentage of area under a continous probability curve from negative infinity to x.
Step-by-step explanation:
The normalcdf means the normal cumulative density function, it can be accessed from the TI Calculators from the DIST section which also includes the normalcdf, invNorm, tpdf and other distribution functions.
The syntax is as follows :
normalcdf (lower bound, upper bound, mean, standard deviation)
Hence, to Obtian the probability that a value is between a and b, with mean, x and standard deviation, s
The normalcdf is written as normalcdf(a, b, x, s)

Answer:
Adults: 75, girls: 100, Boys: 75
Step-by-step explanation:
2/5 x 250 = 100( girls)
3/10 x 250 = 75 (boys)
250 - (100 + 75) = 250 - 175 = 75 (Adults)

Answer:
8) 10 15/16 ft³
9) 20 5/6 ft³
Step-by-step explanation:
Volume of a rectangular prism is
l * b * h,
Question 8
We're given the area
Area = l * b
So we substitute the area for length and breadth.
Volume = Area * height
Volume = 4 3/8 * 2 1/2
Volume = 35/8 * 5/2
Volume = 175/16
Volume = 10 15/16 ft³
Question 9
Volume = 5 * 1 2/3 * 2 1/2
Volume = 5 * 5/3 * 5/2
Volume = 5 * 25/6
Volume = 125/6
Volume = 20 5/6 ft³

Answer:
80.5π cm
Step-by-step explanation:
We want to find the area where the label should go onto the can. If we were to take the label and flatten it onto a 2D surface, we would multiply 11.5 cm by the width, which is equivalent to the circumference of the circle. The circumference of the circle can be calculated using the equation 2πr. The radius is 3.5 cm, so the circumference of the circle is 7π. We multiply 7π by 11.5 to get 80.5π cm.

Step-by-step explanation: Domain means the x values. Since Miguel works between 15 and 25 hours, the appropriate x values (independent variable) are between 15 and 25.
B is wrong because between 100 and 300 would be the range (y values). C is wrong because a specific domain (between 15 and 25) is specified in the problem, and all real numbers would also include negatives, which isn’t realistic for this scenario. D is wrong because a specific domain is specified. Therefore, it couldn’t be all numbers greater than 0.

If the center of a circle is at
(5,-3) and its radius is 4, complete
its equation:
(x – [? ])2+(y - [ ])2= []
Answer:
[tex](x - 5)^2 + (y - (-3))^2 = 16[/tex]
Answer:
(x - 5)² + (y + 3)² = 16
Step-by-step explanation:
(x - h)² + (y - k)² = r²
(h, k) is the center = (5, -3)
r is the radius = 4
r² = 4² = 16

If f(x) = 2x – 3 and g(x) = 4x + 5, what is (f • g)(x)?
Answer:
Place the f(x) expression 2x-3 into the x in the g(x) expression 4x+5, so it will be 4(2x-3)+5; you can expand it out if you want
Answer:
if you mean f(x)×g(x)
the answer will be like that
(2x-3)×(4x+5)=8x²+10x-12x-15=8x²-2x-15
and if you mean f(g(x)) the answer will be like that
f(4x+5)=2×(4x+5)-3=8x+7

Between 06 00 and 10 00,the same day ,the volume of water in a reservoir decreased from 24 000L to 18 000L.What was the average rate of decrease in volume of water, giving your answer in L/h?
Answer:
-1.5 L/h
Step-by-step explanation:
The volume of water in a reservoir decreased from 24.000L to 18.000L between 06.00 and 10.00.
We need to find the average rate of decrease in volume of water. It can be solved as follows :
[tex]Rate=\dfrac{18-24}{10-6}\\\\=-1.5\ L/h[/tex]
The negative sign shows the decrease in volume. Hence, the rate of decrease in volume of water is 1.5 L/h.

In BTR the measure of angle T is three less than four times the measure of angle B. The measure of angle r is third one more than three times the measure of angle B. Find the measure of each angle
Answer:
Step-by-step explanation:
140
Answer:
19° = m∠B
73° = m∠T
88° = m∠R
Step-by-step explanation:
Let x = measure of angle B
then 4x - 3 = measure of angle T
and 31 + 3x = measure of angle R
x + 4x - 3 + 31 + 3x = 180
8x + 28 = 180
8x = 152
x = 19° = m∠B
4(19) - 3 = 73° = m∠T
31 + 3(19) = 88° = m∠R
