Answer:

(130.08, 139.92)

Step-by-step explanation:

Given that:

Mean (m) = 135

Standard deviation (σ) = 30

Sample size (n) = 100

α = 90%

The confidence interval value is obtained using the relation:

Mean ± Zcritical * (standard deviation / sqrt(n))

Zcritical at 90% = 1.64

standard deviation / sqrt(n) = 30 / sqrt(100)

= 30 / 10 = 3

Hence,

135 ± 1.64 * (3)

Lower limit : 135 - (1.64 * 3) = 130.08

Upper limit : 135 + (1.64 * 3) = 139.92

Hence,

Confidence interval = (130.08, 139.92)

Step-by-step explanation:

The measurement interpretation of the division of the expression ¾ ÷ ⅛ will be 6.

Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to answer the problem correctly and precisely.

The numbers are given below.

¾ and ⅛

Then the division between the numbers 6 and 1/3 will be given by putting a division sign between them. Then we have

⇒ ¾ ÷ ⅛

⇒ (¾) / (⅛)

⇒ (¾) × (⁸/₁)

⇒ 6

The measurement interpretation of the division of the expression ¾ ÷ ⅛ will be 6.

Step-by-step explanation:

72km/h = 72,000m/3,600s = 20m/s.

Using Kinematics, we have

v = u + at

= (20m/s) + (-2m/s²)(5s)

= 10m/s.

Hence the velocity will be 10m/s. (or 36km/h)

Step-by-step explanation:

In ordee to round the number 7209 to the nearest thousands, we take a look at the digit in the hundreds place (which is 2).

Since 2 < 5, we round the number itself down to the nearest thousands:

7209 => 7000.

Hence our rounded number is 7000.

Answer:

7000

Step-by-step explanation:

The thousandths place in 7209 is less than 5, the number will change to 7000.

The solution is Option A.

The number of only children with no pets is given by the equation A = 63 and the percentage would be P = 37.5 %

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.

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 data ,

Let the number of only children with no pets be A

Now , the equation will be

The number of siblings with pets = 82

The number of siblings with no pets = 141

The number of only child with pets = 105

Now , let A = 63

So , the total number of children = 105 + 63 = 168

The percentage given is P = 37.5 %

So , the percentage of children with no pets P = ( number of only children with no pets / total number of children ) x 100

Substituting the values in the equation , we get

Percentage of children with no pets P = ( 63 / 168 ) x 100

Percentage of children with no pets P = 0.375 x 100

Percentage of children with no pets P = 37.5 %

Therefore , the value of A is 63

Hence , the number of children with no pets i 63

Step-by-step explanation:

s2 = a2 / n  

a2 =  4.34782608696 if just 1/1 flavour 400/400 was the case.

We are asked to account for 5 flavours 4.34782608696/5

Z test was  0.86956521739 for red candies

s2 = a2/n

a2 = 0.86956521739/1

s2 = 0.86956521739/1  

s2 = 0.87 hundredth place

Answer:

this is confused me so much is it supposed to be a trick or is that a actual question-

Let's write this question as a systems of equations to solve.

x-y=7 (the difference)

x+y=23 (the sum)

Through the process of elimination we get

2x=30

x=15.

With that value of x, we can plug it back into any of the previous equations to get the value of y.

(15)-y=7 (Solve for y)

y=8.

The two numbers are 15 and 8.
