Answer:
0.0882
Step-by-step explanation:
Given that:
Mean(m) = 281
Standard deviation (s) = 33
Probability of weight between 291 and 299 gram
Obtain the standardized score (Zscore):
P (X ≤ 291)
Zscore = (x - m) / s
Zscore = (291 - 281) / 33
Zscore = 10 / 33 = 0.303
P(Z ≤ 0.303) = 0.61906 (Z probability calculator)
P (X ≤ 299)
Zscore = (x - m) / s
Zscore = (299 - 281) / 33
Zscore = 18 / 33 = 0.5454
P(Z ≤ 0.5454) = 0.70726 (Z probability calculator)
Hence, probability of weight between 291 and 299 gram = 0.70726 - 0.61906 = 0.0882

At a hardware store they can cut a rope off of a big roll so you can buy any length you like. the cost of 6 feet of rope is 7.50 how much would you pay for 50 feet of rope.
Answer:
first you'd need to divide 7.50 by 6 which will get you (7.50÷6=1.25) then you would need to multiply 1.25 by 50 which will get you $62.50 (1.25×50=62.5).
Marta walked at 4.9 mile per hour for 0.89 miles. How fa did she walk?
Answer:
2.808 hope this helps :)
Answer:
I think it would be .89 miles because it says that she walked that distance.
Step-by-step explanation:
If it gives you the distance she walked, the speed won't change the distance traveled, only the amount of time paired with speed would change the distance.
June and Armando are each in a hot air balloon. Armando's balloon is at a slightly higher elevation than June's. The two balloons are 100 ft apart
June notices she must look up at an angle of 25° to see Armando in his balloon. How much higher is Armando than June?
Answer:
46.63 ft
Step-by-step explanation:
I've drawn and attached a triangle diagram to represent this elevation and distance of balloons.
Now, from the diagram attached, we can see the angle at which June must look up to see Armando is 25°.
Also, the height of Armando above June is represented by "x".
Thus, using pythagoras theorem, we can find x.
Thus;
x/100 = tan 25
x = 100 × tan 25
x = 100 × 0.4663
x = 46.63 ft
Work out the size of angle x.
Answer:
120°
Step-by-step explanation:
since 60° and x are alternate interior
you get this equation
60° + x = 180
subtract 60 from both sides
x = 120

What is 43 percent of 84
Answer:
36.12
Step-by-step explanation:
43% of 84 can be rewritten to 43% * 84 or 43/100 * 84.
43/100 * 84/1 = 3612/100
3612/100 = 36.12
Answer:3612 you have to mulpliy 43 by 84 and will get 3612

The Stock Market Alexander is a stockbroker. He earns 11% commission each week. Last week,
he sold $7,500 worth of stocks. How much did he make last week in commission? If he averages
that same amount each week, how much did he make in commission in 2011?
Answer: 594 and 30888
Step-by-step explanation:
5400 x 0.11 = 594
594 dollars in commission of one week
52 weeks in a year
52 x 594 = 30888 dollars made in 2011

Trigonometry. Find the value of x. Round to the nearest tenth. I been stuck on it for a while I need help.
Answer:
x= 256.8(rounded)
Step-by-step explanation:
For this problem, use tangent because you have adjacent and are trying to find the opposite side from the angle. Tan(15°)= x/300 so x=300tan(15°)
It was negative, but you probably take absolute value.

If the terminal point determined by t is (-5,-4), then
\sin (t) =

\cos (t) =
;
\tan (t) =
.
Answer:
The trigonometric ratios associated with (-5, -4) are [tex]\sin t \approx -0.625[/tex], [tex]\cos t \approx -0.781[/tex] and [tex]\tan t = 0.8[/tex].
Step-by-step explanation:
Let [tex]\vec u = (x,y)[/tex]. From Trigonometry, we remember the following definitions for the trigonometric ratios, dimensionless:
[tex]\sin t = \frac{y}{\sqrt{x^{2}+y^{2}}}[/tex] (1)
[tex]\cos t = \frac{x}{\sqrt{x^{2}+y^{2}}}[/tex] (2)
[tex]\tan t = \frac{y}{x}[/tex] (3)
If we know that [tex]x = -5[/tex] and [tex]y = -4[/tex], then the trigonometric ratios are, respectively:
[tex]\sin t = \frac{-4}{\sqrt{(-5)^{2}+(-4)^{2}}}[/tex]
[tex]\sin t \approx -0.625[/tex]
[tex]\cos t = \frac{-5}{\sqrt{(-5)^{2}+(-4)^{2}}}[/tex]
[tex]\cos t \approx -0.781[/tex]
[tex]\tan t = \frac{-4}{-5}[/tex]
[tex]\tan t = 0.8[/tex]
The trigonometric ratios associated with (-5, -4) are [tex]\sin t \approx -0.625[/tex], [tex]\cos t \approx -0.781[/tex] and [tex]\tan t = 0.8[/tex].

The measure of Zo is 150°. What is the value of mZb+mZc+mze?
O 90°
ОООО
120°
210°
Answer:
∠b + ∠c + ∠e = 120°
Step-by-step explanation:
From the attached figure,
∠b + ∠e + ∠a = 180° (Linear pair)
Given that, ∠a = 90°
∠b + ∠e = 90° ...(1)
Also,
∠c + ∠d = 180° (Linear pair)
Given that,
∠d = 150°
∠c = 180°-150°
= 30°
Adding ∠c to both sides of the equation (1).
∠b + ∠e + ∠c= 90° + ∠c
∠b + ∠c + ∠e = 90° + 30°
= 120°
Hence, the meaure of ∠b + ∠c + ∠e is equal to 120°

Given the function m(x) = 2x - 10, find x when m(x) = -4
Answer:
Step-by-step explanation:
kinda confusing but ill do my best :/
if what youre saying is m(x) = -4 like x = -4 then do this
plug in -4 for x and solve
= 2(-4) - 10
= -8 - 10
= -18
or are you saying like the whole equation is equal to -4 and we need to solve for x do this
plug in -4 for 'y'
-4 = 2x - 10
then solve for x
6 = 2x
3 = x
sorry if this is confusing but i hope this helps <3

4x + 3y = 16
Answer:
x= - 2, y=8
Step-by-step explanation:
4x+2y=8 ... (1)
4x+3y=16 ... (2)
(1)-(2): -y= - 8
y=8
Substitute y=8 into any equation
Exp: 4x+2(8)=8
4x+16=8
4x= - 8
x= - 2
