Because the ratio is 5:3:2
There are 150 raisins
And since 2 is one less than 3 my estimate would be subtracting 50 from 150 making there be 100 chocolate chips. Then if the unit is 50, 50 x 5 ( 5 in the ratio) would be 250.

The Stanford-Binet Intelligence Scale is an intelligence test, which, like many other IQ tests, is standardized in order to have a normal distribution with a mean of 100 and a standard deviation of 15 points.
As an early intervention effort, a school psychologist wants to estimate the average score on the Stanford-Binet Intelligence Scale for all students with a specific type of learning disorder using a simple random sample of 36 students with the disorder.
Determine the margin of error,
, of a 90% confidence interval for the mean IQ score of all students with the disorder. Assume that the standard deviation IQ score among the population of all students with the disorder is the same as the standard deviation of IQ score for the general population, =15
points.
Give your answer precise to at least two decimal places.
Answers
Answer:
4.11
Step-by-step explanation:
Margin of error equals critical value times standard error.
MoE = CV × SE
For 90% confidence and n > 30, the critical value is z = 1.645.
The standard error is SE = σ/√n = 15/√36 = 2.5.
Therefore, the margin of error is:
MoE = (1.645) (2.5)
MoE = 4.11
The margin of error of a 90% confidence interval for the mean IQ score of all students with the disorder is 4.1125 and this can be determined by using the formula of margin of error.
Given :
Standardized in order to have a normal distribution with a mean of 100 and a standard deviation of 15 points.A school psychologist wants to estimate the average score on the Stanford-Binet Intelligence Scale for all students with a specific type of learning disorder using a simple random sample of 36 students with the disorder.90% confidence interval.According to the given data, the confidence is 90% and n > 30, so the critical value is z = 1.645.
Now, to determine the standard error using the below formula:
[tex]\rm SE = \dfrac{\sigma}{\sqrt{n} }[/tex]
[tex]\rm SE = \dfrac{15}{\sqrt{36} }=\dfrac{15}{6}[/tex]
SE = 2.5
Now, the formula of margin of error is given by:
[tex]\rm MOE = z\times SE[/tex]
MOE = (1.645) [tex]\times[/tex] (2.5)
MOE = 4.1125
So, the margin of error is 4.1125.

x₁ = 5
x₂ = - 2
Step-by-step explanation:Hi there !
x² - 3x - 10 = 0
x² + 2x - 5x - 10 = 0
x(x + 2) - 5(x + 2) = 0
(x - 5)(x + 2) = 0
x - 5 = 0 => x₁ = 5
x + 2 = 0 => x₂ = - 2

The perimeter of a rectangular garden is 40 it. The length is 2 ft more than the width. Find the length and the width of the garden.
Answers
Answer: Length = 11
Width = 9
Step-by-step explanation:
Let x represent the unknown length.
Let x - 2 represent the unknown width.
The perimeter is equal to 2 times x + (x -2)
Equation:
2 (x + (x - 2)) = 40
x + (x - 2) = 40/2
x + x - 2 = 20
2x - 2 = 20
2x -2 + 2 = 20 + 2
The length is: 2x = 22 -> x = 22/2 -> x = 11
The width is: x - 2 = 9
