Answer:
93.75%
This type of problem you have to REVERSE the question...
"at least one tail" is all possibilities EXCEPT "all heads"...
so your answer is 100% - P(4 heads)
P(4 heads) = (1/2)^4 = .0625
1 - .0625 = .9375

A package of 4 pairs of insulated gloves costs $29.16. What is the unit price of the pairs of gloves?
Answer:
7.29
Step-by-step explanation:
A cylinder has a base area of 154 cm² and a height of 20cm. What is its total surface area, in cm?? Use, 22/7
A.1188
B.1200
C.1220
D.1224
Answer:
Hi there!
We've given with the base area and height. We know the formula for base area
Base area = πr²
154 = 22/7 × r²
154 × 7/22 = r²
49 = r²
√49 = r
7 = r
Now
TSA = 2πr(h + r)
TSA = 2 × 22/7 × 7(7 + 20)
TSA = 44(27)
TSA = 1188 cm²
Evaluate the expression when Y=4

Kelly works two jobs. She usually works at a retail store for eight hours during the day and is paid $15.23 per hour by the store. In the evening she works at a restaurant as a manager for 8 hours and is paid $24.50 per hour. How much does she make on average per hour for the day?
Answer:
Kelly makes about $19.87 per hour for the day.
Step-by-step explanation:
Solve for retail store:
15.23 × 8
121.84
Solve for restaurant:
24.50 × 8
196
Add both of her paychecks:
121.84 + 196
317.84
Divide the total by the total number of hours to find the average per hour:
317.84 ÷ 16
19.865
Round to nearest cent:
19.865 is about 19.87

Recall that in Linear Functions, we wrote the equation for a linear function from a graph. Now we can extend what we know about graphing linear functions to analyze graphs a little more closely. Begin by taking a look at Figure 8. We can see right away that the graph crosses the y-axis at the point (0, 4) so this is the y-intercept.
Find a.
Round to the nearest tenth:
2 cm
150
105
a = [? ]cm
Law of Sines: sin A sin B
sin C
b
Answer:
1.8 cm to the nearest tenth.
Step-by-step explanation:
The angle opposite side a = 180 - 105 - 15 = 60 degrees.
By the Sine Rule:
a / sin 60 = 2 / sin 105
a = 2 * sin60/ sin 105
= 1.79315
4x+8=3x+14
please put break it down how you did it
( a+b) ^2-a^2+b^2
kkkkkkkkkkkkkkk
Answer:
It is assumed the question is asking to simplify or factorize:
(a + b)² - a² + b² = a² + 2ab + b² - a² + b² = 2b² + 2abThis is simplified expression.
Factorizing as follows:
2b² + 2ab = 2b(a + b)Step-by-step explanation:
[tex](a + b) {}^{2} - {a}^{2} + b {}^{2} [/tex]
a² + 2ab + b² - a² + b²
Cancelling a²
2ab + b² + b²
2ab + 2b²
Taking 2 and b as common
2b(a + b)
Find the surface area of the cylinder. Round your answer to the nearest hundredth. (12 in, 2 in)
Answer:
300 in^2
Step-by-step explanation:
6^2 π = 36π
36π * 2 = 72π
12π * 2 = 24π
72π + 24π = 96π
96π = 301.5928947.... ≈ 300 in^2

Answer:
[tex]\frac{14}{19}[/tex]
First:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
[tex]\frac{7}{4} \div \frac{19}{8}[/tex]
Applying the fractions formula for division:
[tex]= \frac{7 \times 8}{4 \times 19}[/tex]
[tex]= \frac{56}{76}[/tex]
Simplifying 56/76, the answer is:
[tex]\frac{14}{19}[/tex]
I hope this helps! :)
Answer:
the answer is 14/19
change the mixed numbers to improper fractions then that becomes 7/4 and 19/8 then multiply across 7x8=56 and 19x4=76 that gives you 56/76
Simplifying 56/76,= 14/19
