I need help with this question quick please!!

Answer:

The percentage of males are not at least 172 pounds

P(X⁻ ≥ 172) = 0.26

Step-by-step explanation:

Step(i):-

Given that 74% of 19 -year -old males are at least 172 pounds

Let 'X' be a random variable in a binomial distribution

P( X≥172) = 74% = 0.74

we have to find that the percentage of males are not at least 172 pounds

Step(ii):-

The probability of males are not at least 172 pounds

P(X⁻≥172) = 1- P( X≥172)

                 = 1- 0.74

                 = 0.26

Final answer:-

The percentage of males are not at least 172 pounds

P(X⁻ ≥ 172) = 0.26

Answer:

x ≈ 7.7

Step-by-step explanation:

Using Pythagoras' identity on the right triangle on the right side

let the third side be y , then

y² + 4² = 10²

y² + 16 = 100 ( subtract 16 from both sides )

y² = 84

Using Pythagoras' identity on the right triangle on the left side

x² + 5² = y²

x² + 25 = 84 ( subtract 25 from both sides )

x² = 59 ( take the square root of both sides )

x = [tex]\sqrt{59}[/tex] ≈ 7.7 ( to the nearest tenth )

The monomial [tex](-3m^5)(–2m^4)[/tex]in standard form is [tex]6m^9[/tex]

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants. An algebraic expression is a combination of variables, constants, and mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation.

The variables represent unknown or unspecified values that can take on different numerical values, while the constants are specific, fixed values that do not change.

The mathematical operations are used to manipulate the variables and constants and to create different algebraic expressions.

Given expression ,

[tex](-3m^5)(–2m^4)[/tex]

we know that [tex]a^m * a ^n = a ^ (m+n)[/tex]

[tex](-3m^5)(-2m^4) = 6m^(5+4)[/tex]

= [tex]6m^9[/tex]

Therefore, the answer is [tex]6m^9[/tex] in standard form.

Answer:

DB!

Step-by-step explanation:

Because if you multiply them out, they both equal 6k-30.

-6(5-k)=-30+6k, which is equal to 6k-30.

Hope I helped!

because you can use the distributive property with

-6(5-k)

-6×5= -30

-6×-1k= 6k

so that equals 6k-30

Answer:

13. 5 years

Step-by-step explanation:

First, convert R percent to r a decimal

r = R/100

r = 6.8%/100

r = 0.068 per year,

Then, solve our equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(182,800 / 75,000) / ( 1 × [ln(1 + 0.068/1)] )

t = 13.542 years

Summary:

The time required to get  a total amount of $ 182,800.00  from compound interest on a principal of $ 75,000.00  at an interest rate of 6.8% per year  and compounded 1 times per year  is 13.542 years. (about 13 years 7 months)

Delta Math Solution

Answer:

b; 1/6

Step-by-step explanation:

Answer:

1 : 6

Step-by-step explanation:

From the question given above, the following data were obtained:

Radius (r) = 10 cm

Height (h) = 15 cm

Ratio of TSA and CSA =?

Next, we shall determine the total surface area (TSA) of the cylinder. This can be obtained as follow:

Radius (r) = 10 cm

Height (h) = 15 cm

Pi (π) = 3.14

Total surface area (TSA) of the cylinder =?

TSA = 2πr(r + H)

TSA = 2 × 3.14 × (10 + 15)

TSA = 6.28 × 25

TSA = 157 cm²

Next, we shall determine the curve surface area (CSA) of the cylinder. This can be obtained as follow:

Radius (r) = 10 cm

Height (h) = 15 cm

Pi (π) = 3.14

Curve surface area (CSA) of cylinder =?

CSA = 2πrh

CSA = 2 × 3.14 × 10 × 15

CSA = 942 cm²

Finally, we shall determine the ratio of the total surface area (TSA) and curve surface area (CSA) of the cylinder. This can be obtained as follow:

TSA = 157 cm²

CSA = 942 cm²

Ratio of TSA and CSA =?

TSA : CSA = 157 / 942

TSA : CSA = 1 / 6

TSA : CSA = 1 : 6

Thus, the ratio of the total surface area (TSA) and curve surface area (CSA) of the cylinder is 1 : 6

Answer:

x = -3

y = -8

Step-by-step explanation:

2y = x - 13

3x = y - 1;  let y = 3x + 1

substitute to solve for 'x':

2(3x + 1) = x - 13

6x + 2 = x - 13

5x + 2 = -13

5x = -15

x = -3

solve for 'y':

3(-3) = y - 1

-9 = y - 1

-8 = y

Answer:

(-3,-8)

Step-by-step explanation:

Get one of the variables by themself.

3x = y-1

y = 3x+1

Plug that equation into the other one

2(3x+1) = x-13

Distribute the 2 to 3x+1

6x+2 = x-13

Combine like terms

6x+2 = x-13

-x       -x

5x+2 = x-13

    -2        -2

5x = -15

Divide by 5 on both sides

5x = -15

÷5   ÷5

x = -3

Find y

3(-3) = y-1

-9 = y-1

+1       +1

y = -8

Step-by-step explanation:

3: 3, 6, 9, 12, 15

5: 5, 10, 15, 20

15 is the lcm of 3 and 5

Answer:

15 hrs

Step-by-step explanation:

Time for One pipe = 3 hrs

Amount of tank it can fill in 1 hr = 1/3

Time for Second  pipe = 5 hrs

Amount of tank it can fill in 1 hr = 1/5

Tank they can fill together in 1 hr = 1/3 x 1/5= 1/15

Time it takes to fill full tank = 15/1

Answer:

3x³ + x² - 2

Step-by-step explanation:

a) 3(x squared plus 3x cubed - 2)​

x squared = x²

3x cubed = 3x³

3(x squared plus 3x cubed - 2)​

= 3(x² + 3x³ - 2)

= 3x² + 9x³ - 6

Rearrange according to power

= 9x³ + 3x² - 6

When the expression is divided by 3, it is equivalent to

3x³ + x² - 2
