Which equation can be solved using the expression StartFraction negative 3 plus-or-minus StartRoot (3) squared + 4 (10) (2) EndR

katen-ka-za [31]

Answer: B. 2 = 3x + 10x2

Step-by-step explanation:

This is the concept of quadratic equations; We required to find the type of equation that can be solved using the model that has been used to solve the equation such that the answer is:

[-3+-sqrt(3^2+4(10)(2))]/(2(10))

The formual that was applied here was a quadratic formula given by:

x=[-b+\-sqrt(b^2-4ac)]/2a

whereby from the our substituted values above,

a=10,b=3 and c=-2

such that the quadratic equation will be:

10x^2+3x-2

lawyer [7]

Answer: 3/8, 0.375, 37.5%

Step-by-step explanation:

Count the number of cards with odd numbers that are greater than 4. 5, 7, and 9 are odd numbers greater than 4. There are 3 cards with odd numbers greater than 4. Probability is found by dividing this by the total number of cards, 8. This gets you a fraction of 3/8.

What whole number come before 105

ZanzabumX [31]

The whole number that comes before 105 is 104.

However, it is not the only whole number that comes before 105.

Whole numbers are identified as natural number and zero (0). Meaning the whole number starts with 0 then followed by 1,2,3,4.... so on. Whole numbers are positive numbers without remainders nor fractions.

Whole number that come before 105 range from 0 to 104.

Natural numbers are also called counting numbers; They start with 1. Zero is not a natural number because it cannot be counted.

Integers are numbers which can be positive or negative and it includes zero.

A recent study claims that business travelers spend an average of $39 per day for meals. A sample of 15 business travelers found

4vir4ik [10]

Answer:

The test statistic value 't' = 3.074

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given sample size 'n' = 15

mean of the Population 'μ' = $39

mean of the sample x⁻ = $42

standard deviation of the sample 's' = $3.78

Degrees of freedom ν = n-1 = 15-1 =14

$t_{\frac{\alpha }{2} } = 1.769$

Null hypothesis : There is no significance difference between the means

H₀ : x⁻ = 'μ'

Alternative hypothesis : There is significance difference between the means

H₀ : x⁻ ≠ 'μ'

<u><em>Test statistic </em></u>

$t = \frac{x^{-} -mean}{\frac{s}{\sqrt{n} } }$

$t = \frac{42 -39}{\frac{3.78}{\sqrt{15} } }$

<em>t = 3.074</em>

The test value of t-statistic <em>t = 3.074</em>

<em>The calculated value </em> <em>t = 3.074 > 1.769 at 0.05 level of significance</em>

<em>null hypothesis is rejected</em>

<em>Alternative hypothesis is accepted</em>

<u><em>Final answer</em></u><em>:-</em>

There is significance difference between the means
