Step-by-step explanation:

Answer:

0.969

Step-by-step explanation:

Given that:

Mean lifetime (m) = 520 hours

Variance = 900

Hence, standard deviation (s) = √900 = 30

Probability that bulb will last for at most 576 hours

X ≤ 576

Obtain the standardized score :

Using the relation :

Zscore = (x - m) / s

Zscore = (576 - 520) / 30

Zscore = 56 / 30

Zscore = 1.867

P(Z ≤ 1.867) : using the z probability calculator ;

P(Z ≤ 1.867) = 0.96905

Hence, P(Z ≤ 1.867) = 0.969

Answer:

its 8 cause 2 times x is 40 40+-40= 0 so 2 times 4 is 8

Step-by-step explanation:

Answer: x=5

Step-by-step explanation:

Distribute the 4 to the 2 and 9 and you will get (8x-36)=4.

Then you'd add the 36 to 4 to get 40.

Lastly you'd divide 8 and 40 to get 5. Hope this helps!!!

Answer:

Multiply the normal price of the item by .25 and then subtract that from the normal price.

Step-by-step explanation

[tex]x -(x*.25)[/tex]  

x is the item

Step-by-step explanation:

100%-25%= discounted price= 75%

You do the discounted price divided by 75 to find 1%

do that times 100 to find the pre-discounted price.

e.g

find the original price of a sweater when it was on sale of 25%. the sale price is £15.00.

£15.00 = 75%

15.00 divided by 75 = 1% =£0.20

£0.20 x 100 = pre-sale price = £20.00

The price of the sweater before the sale is £20.00.

Answer:

n=16

Step-by-step explanation:

n/4 + 1 = 5

inverse operations, (subtract the one from both sides)

n/4 = 4

inverse operations, multiply by 4 on both sides, (you're isolating the variable)

n = 16

Answer:

4.5 ounces of yellow and 7.5 ounces of blue will create 12 ounces of the perfect shade of green.

Step-by-step explanation:

1.5 + 2.5 = 4 ounces.

Multiply by 3

4.5 + 7.5 = 12 ounces

So, she needs 4.5 ounces of yellow.

Answer: 2² * 3=12 1,2,3,4,6,12.

A.

Step-by-step explanation: One such number should have 1,2,4,8,16,32 as factors. So 32 is one such number. Swapping 16 with 3,we have 2² * 3=12 1,2,3,4,6,12.

Answer:

-6+x≤15

negative six: -6

plus: +

a number: variable (I chose x)

Less than or equal to: ≤ (an inequality)

fifteen: 15

Answer:

-6 + n ≤ 15

or

n ≤ 21

Step-by-step explanation:

negative six is -6

plus a number would be a variable (I will use n) + n

is less than or equal to would be ≤

fifteen is 15

-6 + n ≤ 15

If you want to solve it, continue

-6 + n ≤ 15

+6         +6

n ≤ 21

I hope that this helps! :)

Answer:

Step-by-step explanation:

Answer:

slope is -6/8, y-int is 3, x-int is 4, this is found by setting the other variable to 0 and dividing -6 by 8 when you subtract 6x from the left side

Step-by-step explanation:

The slope is -3/4, y- intercept is 3 and x- intercept is 4.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

Equation: 6x+ 8y= 24

As, the slope intercept form is

y = mx+ b

where m is the slope, b is the y- intercept.

Now, 6x+ 8y = 24

8y = 24- 6x

y = 24/8 - 6x/8

y = 3 - 3x /4

Thus, the slope is -3/4, y- intercept is 3.

Now, for x- intercept put y= 0

0 =3- 3x/4

3= 3x/4

x= 3 (4/3)

x= 4

The diagram assumes that the angle on the lower left of the triangle is a right angle. If it is not, then I don't think there is a way that this can be solved.

Tan(A) = opposite / adjacent

opposite = 7

Adjacent = 4

Tan(A) = 7/4 = 1.75

A = inverseTan (1.75)
