The correct answer is 96,000

Step-by-step explanation:

To round you look at the thousands place and there is a 9 then you look at the number to the right of it which is 2 and it is lower than 5 since it is lower than five it rounds down so the correct answer is 96,000.

Answer:

96,000

Step-by-step explanation:

If the number on the right of the nearest thousand is lower than 5 the nearest thousand and the numbers to the left of it stay the same, while the numbers on the right turn into 0(zeros) but if the number in the right of the nearest thousand is 5 or grater then the nearest thousand would go up one digit while the numbers on the left of the nearest thousand stay the same, while the numbers on the right of the nearest thousand turn to zeros.

A random sample of 146 recent donations at a certain blood bank reveals that 81 were type A blood. Does this suggest that the ac

Tju [1.3M]

Answer:

We reject H₀ the actual percentage of type A donations differs from 40%

Step-by-step explanation:

Sample information:

sample size n = 146

Type A x₁ = 81 and p₁ = 81 / 146 p₁ = 0,5547

then q₁ = 1 - p₁ q₁ = 1 - 0,5547 q₁ = 0,4453

We choose as significance level α = 5% α = 0,05 α /2 = 0,025

from z-table we find z (c) = 1,96

National % of the population ( μ = 40 % μ = 0,4 )

Test hypothesis

Null hypothesis H₀ p₁ = μ

Alternative Hypothesis Hₐ p₁ ≠ μ

The Alternative hypothesis indicates that the test is a two-tail test

z(s) = ( p₁ - μ )/ √ p₁*q₁ / n

z(s) = ( 0,5547 - 0,40 )/ √ 0,5547*0,4453 / 146

z(s) = 0,1547 / 0,041

z(s) = 3,77

Comparing z(s) and z(c)

z(s) > z(c)

z(s) is in the rejection region. We reject H₀. Sample does not give evidence to support that the actual percentage of type A donations is equal to the national population

What statements is equal to the expression p\11

V125BC [204]

Answer: "p divided by 11" or "p over 11" or "p by 11".

Step-by-step explanation:

We use mathematical statements to express any algebraic expression.

For example: We write 2x as "2 is multiplied by x " or " product of 2 and x".

p+q as "sum of p and q" or "p is added to q"

The given expression is : $\dfrac{p}{11}$

In mathematical statements, it can be written as "p divided by 11" or "p over 11" or "p by 11".

Hence, the statements are equal to the expression $\dfrac{p}{11}$ are "p divided by 11" or "p over 11" or "p by 11".

Prove that ΔABC and ΔEDC are similar.

Lesechka [4]

Answer:

∠DCE is congruent to ∠CBA by the Vertical Angles Theorem and 15 over 5 equals 12 over 4 shows the corresponding sides are proportional; therefore, ΔABC ~ ΔEDC by the SSS Similarity Postulate.

How do I solve for n? 13=n-8

choli [55]

N in (-oo:+oo)

-13 = n-8 // - n-8

8-n-13 = 0

-n-5 = 0 // + 5

-n = 5 // * -1

n = -5

n = -5
