Answer 1

Answer:

z = 156

Step-by-step explanation:

y² = 65²-25² = 4225 - 625 = 3600

(x+25)²-65² = z²

x²+50x+625-4225 = z²

x²+50x-3600 = z²    ....(1)

x²+60² = z²

x²+3600 = z²   ....(2)

(1)-(2): 50x - 7200 = 0

50x = 7200

x = 144

check: x² + y² = z²       144² + 60² = 24336 = z²       z = 156

(25+144)²-65² = z² = 28561 - 4225 = 24336            z = 156

Since deposited amount si $3,400

The interest rate is 1.95%

And, the time period is 2.5 years

So, here the balance should be like

[tex]= 3400 \times (1 + 1.95\%)^{2.5[/tex]

Answers

Answer:

Third side = 3√3

Step-by-step explanation:

Apply pythagorean theorem, which is a² + b² = c²

Where,

a = ?

b = 3

c = 6

Substitute

a² + 3² = 6²

a² = 6² - 3²

a² = 27

a = √27

a = √(9 × 3)

a = 3√3

Question 3 of 10
You roll two number cubes.
Let event A = You roll an even number on the first cube.
Let event B = You roll a 4 on the second cube.
Are the events independent or dependent? Why?
A. Independent, because the outcome of the first roll doesn't affect
the outcome of the second roll.
B. Independent, because they have no outcomes in common.
C. Dependent, because both cubes have six sides.
D. Dependent, because 4 is an even number.

Answers

Answer:

D

Step-by-step explanation:

They are both even numbers the 4 is seperated into 2,2 and if 4 is an even and event A is even it would be dependent

What is the measure of angle ACB?

Answers

Answer: 48

Step-by-step explanation:

A soft-drink machine is regulated so that the amount of drink dispensed is approximately normally distributed with known standard deviation, sigma. Given a random sample of n drinks and the sample mean, x-bar, you find a 90% confidence interval for the mean of all drinks dispensed by this machine. Then you calculate a 90% confidence interval (same confidence level) using a larger sample, for example (n 20) drinks. Also, you notice that the sample mean, x-bar, is the same for both samples.

Required:
Was this a reasonable decision?

Answers

Answer:

This is  a reasonable decision because the sample size has no effect on the 90% confidence interval

Step-by-step explanation:

90% confidence interval

larger sample size = 20

condition : sample mean ( x-bar ) is the same for both samples

This is  a reasonable decision because the sample size has no effect on the 90% confidence interval

from condition 1 :

Amount of drink dispensed is normally distributed with known standard deviation , given a random sample of n drinks and the sample mean at a confidence interval of 90%

for condition 2 :

sample size = 20

mean = 2.25 ( assumed value )

std = 0.15 ( assumed value )

Z = 1.645 ( Z-value )

determine the 90% confidence interval

= mean ± z [tex]\frac{std}{\sqrt{n} }[/tex]

= 2.25 ± 1.645 [tex]\frac{0.15}{\sqrt{20} }[/tex]

= 2.25 ± 0.0335 = ( 2.2835 , 2.2165 )

Describe how you calculated surface area. Provide a few examples of how the concept of surface area can be used in the real world!!

Answers

The formula to find the surface area depends on the shape. However, you can find the area of each face of the shape, then add them all together. This concept of surface area can be used in the real world, and is everyday. When drawing blueprints or building a house, architects need to calculate surface area.

Answer:

Halo!!! i wrote my answer below your epic btw

Step-by-step explanation:

you first have to break up the surface of the shape into smaller shapes so that they are easier to work with. you then calculate all of the shapes and add them together. this can be used in the real world to find the area of houses when you need to find how much space an area of the house has.

(a) An angle measures 51°. What is the measure of its supplement?
(b) An angle measures 27°. What is the measure of its complement?

Answers

Answer:

a - 129

b - 63

Step-by-step explanation:

for a - supplementary angles add up to equal 180

so to find the measure of its supplement we subtract the given angle from 180 180-51=129

so the measure of a supplement angle is 129

for b - complementary angle add up to equal 90

so to finds the measure of its complement we subtract the given angle from 90

90-27=63

so the measure of its complement is 63

Answer:

(a) An angle measures 51°. the measure of its supplement=180-51=129°

b) An angle measures 27°. the measure of its complement=90-27=63°

I need help plz 6x-5=2x+7

Answers

Answer:  x=3

Step-by-step explanation; Add 5 to both sides of the equation

6x-5+5=2x+7+5

simplify: add the numbers

6x-5+5=2x+75 = 6x=2x + 7+5

6x =2x + 7+5

6x=2x +12.

subtract 2x from both ides of the equation: 6x=2x + 12

6x - 2x =2x + 12-2x6

combine like terms  u should get 4x= 12

divided both sides of the equation by the same term 4x=12  4x/4 =12/4

Cancel terms that are in both the numerator and denominator u should get  x=12/4

divided the numbers and ur answer is X=3

Answer:

[tex]NO= 31.2[/tex]

Step-by-step explanation:

See attachment for triangle

From the attachment, we have:

[tex]KL = 51.6[/tex]

[tex]LM= 38[/tex]

[tex]OP = 23[/tex]

Required

Find NO

This will be calculated using the following equivalent ratios:

[tex]NO : OP = KL : LM[/tex]

This gives:

[tex]NO : 23= 51.6: 38[/tex]

Express as fraction

[tex]\frac{NO }{ 23}= \frac{51.6}{ 38}[/tex]

Make NO the subject

[tex]NO= \frac{51.6}{ 38} * 23[/tex]

[tex]NO= \frac{51.6* 23}{ 38}[/tex]
