Which of the following numbers is divisible by 2, 5, and 10?
A. 101
B. 125
C. 342
D. 550
Answers
Answer: D. 550
Step-by-step explanation: Among the choices, 550 is the right answer, because simply it is divisible by 2, 5, and 10, unlike the other choices that are not divisible by 2, 5, or 10.
550 ÷ 10 = 55
550 ÷ 5 = 110
550 ÷ 2 = 275
550/2 = 275
550/5 = 110
550/10 = 55
Shade 1 circle. Shade 9/4 more
Answers
Answer:
For the first one, shade in 1 circle at the start
Then shade in 9/4 more, so you would fully shade 2 more because every 4 equals 1.
Then shade 1 quarter of the next circle, or 1 of the 4 portions of the next circle.
____________________________________
For the second one, shade in 2 circles at the start
Then shade 8/5 more, so fully shade one more because every 5 numbers equals one shaded circle.

There is no association between the two variables if the correlation is 0.hintlinks to an external site. textbook pageslinks to an external site is False statement.
A correlation of zero means that there is no linear relationship between two variables, however, this does not necessarily mean that there is no relationship at all. It's crucial to keep in mind that correlation does not equal causation.For example, two variables may have no linear relationship, but still be related in some way, such as through a third variable or a non-linear relationship. Therefore, correlation does not necessarily mean that there is no relationship between two variables.

write the expression as a single logarithm with coefficient 1. assume all variables represent positive real numbers. 1/4logbx^5y^7-4/7logbx^4y
Answers
the formula as one logarithm with a coefficient of 1 with a expression. assume all variables represent positive real numbers. 1/4logbx^5y^7-4/7logbx^4y is logbx^4y^11/28
Since the coefficients of the expression of two logs are not the same, we need to adjust the exponents in order to combine them into one logarithm. Since the first logarithm has a coefficient of 1/4, we multiply the exponent of the second logarithm by 4/7 to get 4/7*4 which is equal to 4. We then add 4 to the exponent of the first logarithm to get 11. This gives us a combined logarithm of logbx^4y^11/28.

The price that is the Second standard above the mean, if the mean is $10000 and the standard deviation is $500 is $18000.
What is mean?The central tendency along the median and mode of a probability distribution is measured by the mean. It is also known as "expected value."
Given:
The mean, m = $17000,
The standard deviation, σ = $500
Calculate the second standard deviation as shown below,
Second standard deviation = mean + 2 × standard deviation
Second standard deviation = 17000 + 2 × 500
Second standard deviation = 17000 + 1000
Second standard deviation = $18000
Therefore, the price that is the Second standard above the mean, if the mean is $10000 and the standard deviation is $500 is $18000.

Show your work. 5y 2(3y − 1) = ⬜y − (y 2)
Answers
we can add 2 to both sides to get 3y = -y2 + 2, which simplifies to 3y = -(y2 - 2).
5y + 2(3y − 1) = 8y - (y2)
5y + 2(3y - 1) can be rewritten as 5y + 6y - 2.
Then, we can combine like terms on the left side to get
11y - 2.
On the right side, we can combine like terms to get 8y - y2.
Now, we have 11y - 2 = 8y - y2. We can subtract 8y from both sides to get 3y - 2 = -y2.
Finally, we can add 2 to both sides to get 3y = -y2 + 2, which simplifies to 3y = -(y2 - 2).

Answers
Babies will not fall asleep more quickly when they hear the sound of a recorded heartbeat by opposite of null hypothesis.
The researcher has proposed a hypothesis that babies will fall asleep more quickly when they can hear the sound of a recorded heartbeat. To test this hypothesis, the researcher must develop a null hypothesis. The null hypothesis is the opposite of the researcher's hypothesis and states the expected outcome if the researcher's hypothesis is false. In this case, the null hypothesis is that babies will not fall asleep more quickly when they hear the sound of a recorded heartbeat. To test these hypotheses, the researcher must design a study and collect data to determine if the hypothesis is true or false. The researcher must also consider variables that could affect the outcome of the study, such as the age of the babies, the type of recorded heartbeat, and any other factors that could impact the outcome. The results of the study will then be used to either reject or accept the null hypothesis and determine if the researcher's hypothesis is true or false.

Answers
Answer:
Account A = $20.8
Account B = $
Step-by-step explanation:
how much is the principal in each account?
Formula = (P x R x T)/100
Account A: -
2.00 = P(3.2)(3) / 100
(2 x 100) / (3.2 x 3) = P
P = $ 20.8
Account B: -
20.7 = P(3.2)(18) / 100
(20.7 x 100) / (3.2 x 18) = P
P = $35.9
Which account earned you the most interest the first month?
Account A: -
3 months ----> $2
1 month ----> $x
x = 2 / 3
x = $0.67
Account B: -

1 month ----> $y
y = 20.7 / 18
y = $1.15
Account B has earned more as 1.15 > 0.67 ( 1.15 IS greater than 0.67)

Show that the function f(x) = x + 5x + 1 has exactly one zero in the interval (-1,0). Which theorem can be used to determine whether a function f(x) has any zeros in a given interval?
Answers
The function f(x) = x + 5x + 1 has exactly one zero in the interval (-1, 0). To prove this, we can use the Intermediate Value Theorem.
This theorem states that if a function f(x) is continuous on an interval [a, b] and if its values at a and b have opposite signs, then there exists at least one root (zero) of the function in the interval (a, b). Therefore, since f(-1) = -6 and f(0) = 1, both of which have opposite signs, the Intermediate Value Theorem can be used to conclude that there exists at least one root of the function in the interval (-1, 0).
Furthermore, since the function is a quadratic function of the form f(x) = ax2 + bx + c, it is known that a quadratic equation can have at most two roots (zeros) (in a given interval). Therefore, since the Intermediate Value Theorem implies that the function f(x) has at least one zero in the interval (-1, 0), it follows that the function has exactly one zero in the interval (-1, 0).

Answers
The cost of each shirt and pair of pants is $11 each.
Let us represent the shirt by x and pair of pants by y. So forming the equation based on the information. Equation for items bought by me -
x + 3y = 44 : Equation 1
Equation for items bought by my friend -
3x + y = 44 : Equation 2
Performing multiplication of equation 1 with 3
3x + 9y = 132 : Equation 3
Performing subtraction of equation 2 from equation 3
3x + 9y = 132
3x + y = 44
We get -
9y - y = 132 - 44
8y = 88
y = 88/8
Performing division
y = 11
Keep the value of y in equation 1
x + 3×11 = 44
x + 33 = 44
x = 44 - 33
x = 11
