here,

f(x)=x-4

then, f(-3.2)=(-3.2)-4

[ replace the value of x in the equation by -3.2]

therefore,f(-3.2)=-7.2 answer....

Answer:

y = -(x+1)^2 +3

Step-by-step explanation:

Translating f(x) left by 1 unit replaces x with x+1.

Translating f(x) up by 3 units replaces f(x) with f(x)+3.

Reflecting f(x) over the x-axis replaces f(x) with -f(x).

When y = x^2 is reflected over the x-axis, it becomes ...

y = -x^2

When y = -x^2 is translated 1 unit left, it becomes ...

y = -(x +1)^2

When y = -(x+1)^2 is translated 3 units up, it becomes ...

y = -(x +1)^2 +3

A researcher is conducting a study of charitable donations by surveying a simple random sample of households in a certain city.

nirvana33 [79]

Answer:

H0: p ≤ 0.50

Ha: p > 0.50

Step-by-step explanation:

The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.

For the case above;

Let p represent the proportion of households in the city that gave a charitable donation in the past year

The null hypothesis is that the proportion of households in the city that gave a charitable donation in the past year is not more that 0.50

H0: p ≤ 0.50

The alternative hypothesis is that the proportion of households in the city that gave a charitable donation in the past year is more that 0.50

Ha: p > 0.50

X/6 = 10/9 improper fraction in its simplified form

FinnZ [79.3K]

Answer:

$\frac{x}{6} = \frac{10}{9} \\ \therefore \: 9 \times x = 6 \times 10 \\ \therefore \:9x = 60 \\ \therefore \:x = \frac{60}{9} \\ \therefore \:x = \frac{20}{3} \\ \: \: \: \: \: \: \huge \red{ \boxed{\therefore \:x = 6\frac{2}{3} }}$
